  2. Questions on ORION Meeting invite from David Fields.
  3. Call for BOD Nominations.  Need three nominations for the board to replace or retain BOD members, Floyd Glick, Dave Molter, and Bill Miller by Feb 3rd.
  4. BOD Initiative

In 2019 and 2020 we accomplished a lot of the big goals that we had been working on for a number of years including (H1) Hydrogen Line mapping, Tropospheric scatter communications, Pulsar detection, and EME.  Now that we have those and can replicate them at will, we have to ask ourselves, what else can we do and what direction(s) should we go in? In my opinion here are several key areas or categories that the org. needs to address with some more detailed plans.

1. Continued Infrastructure upgrade and maintenance

2. Instrument and electronics upgrades and additions

3. Scientific discovery, theory testing, and publication

4. Educational programs and events for members and students

5. Public outreach and member recruitment

6. New observation initiatives

  1. Science Fair:  Letter from PPRSF below.  The Science Fair will be on Feb. 18-20.

Hello Bill,

Please send us a list of your special award judges and their email contact information by February 10, 2021.

We will send you and your judges an email with the details and code to view projects in the virtual showcase.

The attached letter outlines the information for this year’s fair.

We are looking forward to your participation in the virtual science fair and are hoping that next year will be an in-person event.


Carol Bach, Karen Crosson and Lynne Williams 

  1. Our Site is photogenic!   Andrew Miller, another photographer based out of Denver would like to do a project on the site.
  2. Front Range 6 Meter  Group.   Paul Sobon sobonpaul[at]gmail.com The group would like an open house virtual presentation on Wed. , Feb 10th at 6:30 opening at 7PM. Bill is working on a general presentation.
  3. Chad Carter was in Haswell on Friday working on the camera on the large grain elevator.  Did anyone call him into the work trip Saturday. www.car-telenterprises.com 785-564-0118 cell.  Ray sent him email but he didn’t show at the site Saturday so probably had to return to home base.
  4. Planet Walk:
    • Bill will write an endorsement letter and have the DSES Board modify and approve for Planet Walk Colorado Springs. See https://www.planetwalkcs.org/ 
  5. Rich:  See all the notes about the site visit from Saturday Jan 23rd.
  6. See the DSES Science Meeting 1-25-2021 slides PDF from Dr. Rich Russel. http://dses.science/wp-content/uploads/2021/01/DSES-Science-Meeting-1-25-2021.pdfhttp://dses.science/wp-content/uploads/2021/01/DSES-Science-Meeting-1-25-2021.pdf
  7. Saturday Power Glitch: A Mains power glitch caused an upset of the system and that drove the dish to the electrical stops. Rich believes that we should have a UPS or backup battery power on the tower electronics, including the Raspberry Pie and Ethernet Switch and on the Ethernet Switch and computer in the trailer to prevent this.  Bill suggests that anytime the dish is active the operators should monitor its position on the CCTV and use the panel VFD switch to kill the drive if not in control.  In this particular case the watch dog timer in the controller didn’t stop the drive because the computer was still sending updates.
  8. Marc Slover took some pictures while at the site up until about 9PM when the clouds came in.                  
  9. Dan Layne came down for the first time and he and Ray had a good conversation about the systems and the site.

DSES Pulsar Observing on September 12, 2020

Text and photos by Gary Agranat. Analysis pdf by Rich Russel.

On Saturday September 12, 2020 an observing team of Rich Russel, Bob Haggart, Bill Miller, and Gary Agranat spent the day observing pulsars. This is the first observing session since we recalibrated the 60-foot antenna azimuth pointing the weekend before. The team observed 3 pulsars we had not seen before. Plus several other pulsars were attempted. The team spent the whole day at the site, from about 9 AM to 7 PM.

The pulsar signals are so faint that we cannot detect them directly. To observe them, we have to point to the correct celestial coordinates and then track that point as the Earth rotates. While we are pointed, our computer accumulates the signal data. We need at least a half hour continuously tracking the position. At this session some of our observing runs lasted 2 hours, for the fainter objects. At previous sessions we have tracked for as long as 4 hours.

After the observing track, we have our software process the data. The random background noise should cancel itself out. But the pulse signals should build up with time. If we have the correct timing interval of the pulses, and if everything else is working, the computer display will show the pulses, and several other parameters.

Pulsars are very unusual objects. These are what remain of massive stars (greater than 5 solar masses) after they use up all their fuel for nuclear burning. These more massive stars fuse heavier and heavier elements at their cores until they start to fuse iron from silicon. Unlike the fusion of other elements, iron requires energy to fuse, rather than produce energy. The sudden reduction of energy at the core drops the temperature and pressure there. The pressure at the core is no longer enough to counter the weight of the star’s material above it. Gravity is now the stronger force, and the material above collapses in on the center. The pressure and temperature at the core then becomes even higher, which starts new reactions that fuse the matter at the center to neutrons, and and which also generates neutrinos. The outer layers falling in at great speed bounces back out. The result is a supernova explosion. What remains is the neutron star at the center. It is extremely massive and compact. And like an ice skater rotating faster as the arms are brought in, the star’s rotation speeds up immensely. The star’s magnetic field also has become compressed and much more intense. Charged particles will rotate around the magnetic field lines, with very high energy. Whenever charged particles are forced to deviate their paths from a straight line they emit electromagnetic energy, like visible light and radio. At the neutron star’s poles, this energy is channeled out, with immense energy. Because the magnetic poles are generally not at the same spots as the rotational poles, the beam of this light and radio is spun around like a light house. If Earth happens to be in the path of such a beam, we detect that as a pulsar. So that’s what we’re observing.  These neutron stars are hundreds and thousands of light years away.

Pulsars were first discovered by accident in 1967, by Jocelyn Bell (now Jocelyn Bell Burnell) who was then a graduate student at Cambridge University. Bob contributed a recent photograph of her, posed by some radio telescopes. We now proudly have that displayed on the wall above our computer displays.

Because the observing runs take a while, for this session we decided to try watching some videos. Bob brought a DVD player and a large monitor. Gary brought some educational videos, including one about the Crab Nebula and pulsars. Rich brought some movies.

This is a summary of our observing results: http://dses.science/wp-content/uploads/2020/09/11-Pulsars-Observed-so-Far-9-12-20.pdf.

On this work trip the team also inspected damage to our ham radio antennas, damage probably from the storm weather over the past months. 7 radials at the base of the vertical antenna were damaged. And the 3 element Yagi antenna on tower was slightly tilted along its longitudinal boom.

Tumbleweeds also had accumulated again at the bunker ramp. Some of the surrounding fence had also been damaged from the weather. Rich Russel brought some fencing to use in the future, to place over the immediate entrance path to the bunker door.

Repair of the ham antennas and ramp clearing will be planned for a future work trip.

Below is a photo narrative of the day’s work.

It was an excellent day’s work.

At the start of observations, we point to and observe a pulsar with a strong signal that we know we should be able to reliably receive and analyze. If we cannot detect it, that indicates something is wrong with our system. We would then troubleshoot rather than waste our time trying to observe. Here the antenna is pointing to a pulsar we use as a reference source, B0329+54. It is located in the circumpolar sky to our north, so it is always visible above the horizon for us.
Bill Miller, Rich Russel, and Bob Haggart starting observations in the Operations Trailer.
After we checked our equipment and processes, we tried looking for some pulsars that were relatively low on the horizon to our south. Objects that appear to the south are above the horizon only briefly. They rise in the southeast, as the Earth turns they continue to rise in a shallow arc above the southern horizon, then soon set in the south west. If we want to try to observe them, we have just a short window of time to find and track them. Being low on the horizon adds some bias errors and attenuation to the observations. At this session we didn’t succeed in observing any pulsars that were close to the southern horizon.
On this run, the display shows we did not get good data. The software is attempting to synchronize our data with an expected pulse period. In the top window display that is open, for good data we would expect to see clearly spiked peaks rising from a lower noise floor. And in the white rectangular box below that, we would expect to see a signal at that timing accumulate under such spikes. There is no pattern of periodic data. The white box to the right shows timing at the bottom with radio frequency at the side (going up). Because the pulsar signal is broad band (it is spread broadly over a wide range of frequencies), we would expect to see a continuous line of signal from bottom to top, across the frequencies. But we do not see that. (You can click this image to enlarge it.)

The two graphs in the center right tell us we don’t have a definitive measure of a pulse rate, and a steady change in pulse rate. The pulsars are generally slowing down with time, at a very slow but measurable pace. The display is showing the algorithms cannot fit a pattern. If it could, the two peaks would both be centered.
Our Operations Trailer
Our antenna site is surrounded by farm fields.
Rich and Bob are checking data for each next pulsar we attempt to observe. Besides the celestial coordinates, we need to know the expected energy flux. If the signal is weaker, we need to observe and track on the object for a longer period of time. We also need to know the expected pulse timing and several other parameters.
We have up in our control room a framed photo of Jocelyn Bell Burnell, contributed by Bob Haggart. She discovered pulsars serendipitously while she was a graduate student at Cambridge University in 1967.
Rich is assessing a good data set we just got. Here you can see the distinctive pulse timing spikes in the upper left. In the center white plot, you see two straight lines, representing the pulsed signal, across the spectrum of frequencies we observed (we observe across a bandwidth of 10 MHz). At the right, the software found a good analysis for the rate and change of rate of the pulses. The bottom plot slopes downward slightly to the right. That is showing us the dispersion of the signal, something we expect to see. As the pulsar radio signal travels through interstellar space, it has to go through dust and magnetic fields. The effect is that the longer the radio wavelength, the slower the signal will propagate through space. Therefore the longer wavelength signal will arrive slightly later than the shorter. This is an indirect measure of the distance to the pulsar. If the algorithm was just trying to make sense of random noise, we would not see this result in our data. (You can click this image to enlarge it.)
This is a close-up of our SYSTEM 1 software display for pointing our dish antenna. The antenna now can be pointed manually or with several levels of automation.

The first accomplishment was to translate the actual azimuth and elevation pointing angles of the antenna through encoders with digital readouts. That azimuth and elevation angles were then correlated with the celestial coordinates at the given time. That required a good timing reference, as well as an accurate fix on our longitude and latitude. We now take care of that timing and position fix with GPS.

The upper part of the screen shows the direction the antenna is aimed at, in both azimuth and elevation angles, and the celestial coordinates of Right Ascension (RA) and Declination. There is more on the right side that was added later which I will discuss shortly.

The next development was to have a visual reference of the celestial sky, with its coordinate grid system and celestial objects we are interested, displayed on the computer, together with where the antenna is pointing. You see that display in the lower half of the screen. How wide a beam angle our antenna can see (like the field of view you see in an optical telescope) depends on the wavelength of the radio waves we are using. At a wavelength of 70 centimeters (about 400 MHz frequency), the beam width is about 2 degrees for our dish antenna. At wavelength of 21 centimeters (about 1420 MHz where the spectral line of neutral hydrogen is), the beam width is about 0.8 degrees. The software calculates the appropriate beam width and shows that as a circle on the display.

Within the last three months, our software team succeeded in creating a system that will now automatically point and keep tracking a celestial object or any other sky position. As part of this package, the software has a database of celestial objects we may be interested to look at, with their celestial coordinates. The database is updatable. If an object we want is in our database, it will appear on our sky coordinates display, we can point to it with our cursor, and the antenna will slew to point to it and then track it. We can also enter data manually. The software and hardware have safety stops, so that the antenna cannot be pointed below a certain limit above the horizon. And the antenna has azimuth limits, so that our cables to the antenna feed in the pedestal don’t wrap around with too many turns. The software also is programmed to avoid direct pointing towards the sun.

Because it makes the display much more user friendly, the display shows the visible stars and constellations as well. (You can click the image to enlarge it.)
This screen is how we set our data parameters. And the display at lower left shows the signal coming in. The blue line is the data signal, across the bandwidth of 10 MHz, here centered at 420 MHz.

The green line shows the peak maximum of the signal over the course of the run. Earlier in the day we were seeing persistent radio signals, for us interference, at around 390, 406, 408, 410, and 432 MHz.
We were concerned that one possible cause of problems with some of our data was the sun being close in angle to our pointing. We were never closer than 25 degrees from the sun. But we are wondering if the sun still might heat our preamplifiers at the feed focus of the antenna.
The next set of photos are close-ups of the damage seen on the ham radio HF antennas. This is the tower with the 3-band Yagi. There is a slight tilt along the main boom.
7 radials at the multi-band vertical antenna were also damaged. 5 severed at the lugs, which suggests metal fatigue from repeated moving in the wind. 2 were severed in their middles, which suggests some debris may have impacted those from the winds.
Some of the fence damage by the bunker.
The bunker ramp filled with tumbleweed again.
Closeup of the 408 MHz feed and the feed mount at the focus of the 60 foot dish antenna.
A closeup of the display we now use for pointing the dish antenna for astronomical observing. At the upper right, we can acquire the celestial coordinates from our database, or we can manually type in the needed data. The lower part of that window shows the actions the control system is executing, that is if it is slewing to an object, tracking, holding steady, or something else. The lower display shows the celestial sky, the coordinates, our antenna beam, as well as naked eye objects and constellations.

DSES Sept 19, 2020 Pulsar Observing Trip Observes 2 More Pulsars

Bob Haggart and Rich Russel did an observation all nighter on Friday/Saturday (September 19, 2020, GMT) and observed 2 pulsars.
VELA (B0833-45) is one of the strongest pulsars at 5 JY while B1946+35 is at 0.145 JY.
DSES is one of the most northern amateur stations to detect VELA. We detected it in 15 minutes at 5 to 6 degrees elevation.
This make 13 pulsars and puts us 5th on the international amateur pulsar hunter list. http://www.neutronstar.joataman.net/

DSES Pulsar Observing Team netted 5 new pulsars!

The DSES team of Rich Russel, Ray Uberecken, and Glenn Davis observed for pulsars on Saturday September 5, 2020 at the DSES 60-foot dish antenna at Haswell, CO.

The team successfully observed 5 pulsars which we hadn’t been able to detect before.

The success is attributed to the calibration of the antenna pointing system and the new automatic tracking system developed by the System 1 team.

We started with calibrating the azimuth of the antenna (it was 2.5 degrees off!) Elevation was good. Glenn put the offset in the auto tracking system and we were able to detect the B0329+54 pulsar within 30 minutes. (We use the B0329+54 pulsar, the first one we successfully saw last May, as a starting reference. If we can observe this, we know our system is working.) Every pulsar we looked at after that was detected – we just ran out of time for more!

It is possible we missed observing previous pulsars because our pointing accuracy was off.

See the slide set for our observation summary.


We are pretty sure we observed the Crab pulsar. The last slide shows an analysis of the time between pulses we measured for the Crab pulsar, compared to the standard reference database.

More detail to come at the next science meeting

Our total pulsar count is now 8!

2020-07-27 DSES Science Meeting Notes

Welcome to the July DSES Science meeting 7/27/2020

2020-07-27 DSES Science Meeting Notes:                                                            by Bill Miller

We had 14 participants in the virtual science meeting today:  Thanks everyone for joining.

Participants: Dr. Rich Russel,  Ray Uberecken, Ted Cline, Jonathan Ayers, Ed Corn, Gary Agranat, Glenn Davis, Jim Madsen, Bob Haggart, Jon Richardson, Dave Schick, Don Latham, Tony Bigbee, Bill Miller

Agenda and notes; See the Zoom Recording for more detail: https://us02web.zoom.us/rec/share/u50vfrXt12hJbKf341OCGbJmA8fIaaa80ylL-

  1. Discussion of needed policy on site installs and changes 
    1. We have had a number of site conflicts of late.  These have resulted in a lot of waisted installation and observation time and frustration as well as hard feelings between members and damage to the dish, and operations center.
    2. General Proposal:  I have often said that if you see something that needs improvement and you have the skill to do it, take it on and just do it.  We need to qualify that with a little more process. In order to improve the site, equipment and observation capability and move the organization forward we often need to make changes.  The Engineering meeting is where we coordinate and plan for these changes.  If not previously planned and you are on site and need to make a change to a significant system you must call the person who installed or last modified that system and discuss it with them prior to removing, modifying or replacing it. 
    3. Use the Engineering Meeting for what it was intended.
    4. Be considerate and helpful to each other.
    5. Communication and coordination of equipment changes should not be a problem and further conflicts will have to be dealt with.
    6. We will need to repair the damage.
    7. We all have a common goal to improve the facility and equipment.  Let’s not have these issues.  When in doubt, Ask.
  2. We will potentially have photographers on site Thursday or Saturday for comet picture opportunity.  Would like to have a member on site to give access and keep the photographers out of trouble. Any volunteers?
    1. Don Savage don.savage54 (at) gmail.com is coordinating 4 or 5 night sky photographers.
    2. We will have them sign a Liability Waver
  3. July-August Events:
    1. The SARA virtual Eastern Conference will be held on Saturday and Sunday the 1st and 2nd of August.   See the SARA web site for info and payment.
    2. Comet C/2020 F3 (NEOWISE) is currently in the constellation of Ursa Major. The current Right Ascension is 11h 45m 40s and the Declination is +36° 12’ 10”
    3. Additional pulsar observations. Please post planned dates and attendance
    4. Additional SETI Observations. Please post planned dates and attendance.
    5. Open house is cancelled for CoVid19, but we may do a small member camp out if some members would be interested in that.
    6. We will also assemble a virtual Open House presentation for various usage such as public outreach, education, fundraising and general interest.
    7. The Perseids will peak on Aug 11-12. On these nights, the moon will be 47% full.
    8. The next dark sky moon phase is Aug 13th through Aug 21.
  4. Glenn gave an overview of what was done recently on the System 1 Automatic Tracking HW and SW.  New features include:
    1. Automatic Tracking
    2. RA and Dec track automatically
    3. Az/El position command
    4. Track Moon Command
    5. Stow command

Tracking stayed within the bore site during the whole 5 hr. evening session.

Need to do more training, Glenn and his wife will go to the site tomorrow and draw up a training presentation and checklist.


  1.  Sun exclusion track but there is a pop up on the screen that you are in the sun exclusion area.
  2. It would be nice to have a Raster Scan capability to map Object Hi Emissions and to help pointing accuracy.
  3. Rich provided his presentation on Pulsar, Fast Radio Burst and other experiments and observation we can do.

5. Rich gave high praise and kudos to the System 1 team to get a very high quality tracking and control complete. Very clean system design and implementation from Glenn Davis, Lewis Putnam and Phil Gage.  Much praise.

Deep Space Exploration Society 3rd pulsar observed on Saturday July 11, 2020

By Dr. Richard Russel, DSES Science Lead

The pulsar, B1133+16, was observed on the 60 ft dish antenna by Rich Russel and Ray Uberecken after 4 hours of tracking and collecting data on the pulsar.

This pulsar is the weakest object observed by DSES at 0.257 Janskys!

The pulsar is noted for having a “conal double” peak in its profile. Our observation picks this out very well.

The PRESTO analysis program results are shown below.

The conal double plot is produced from the raw data and plotted in excel.

PSR B1133+16 is located at RA 11h 33m 27s Declination +16.07°, in the northeast part of the constellation Leo. It was observed with a pulse period of 1.187 seconds. Our center frequency was 417 MHz, and we used a 10 MHz bandwidth.

(The name B1133+16 conveys the celestial sky coordinates, referenced to a standard year epoch. In this case the B indicates the position is from the year 1950, the “Besselian” year, named after the German astronomer Friedrich Bessel.)

Congratulations to the entire membership for turning the DSES dish into a world class scientific instrument!


Dr. Richard Russel

DSES Science Lead

“Our second confirmed pulsar!”

Rich Russel reports we observed our second confirmed pulsar, “We got B0950+08 today!!!!!!” The observing team was Rich Russel, Ray Uberecken, and Bob Haggart. The team did the observing and made the measurement at the Plishner radio telescope site with the 60-foot antenna yesterday on July 4, 2020. Congratulations to the team! And congratulations are due also to all of the DSES members who have been working hard to restore the 60-foot dish antenna and develop is capability as a working scientific tool! This is a long time coming.

A brief information entry about PSR B0950+08 in Wikipedia: https://en.wikipedia.org/wiki/PSR_B0950+08

Meanwhile, the report of our first pulsar observation on May 2nd, of pulsar, B0329+54 (J0332+5434), was just published in the May-June journal of the Society of Amateur Radio Astronomers: First Deep Space Exploration Society (DSES) Pulsar Captured on the 60-ft Dish
