Observations using the 60-foot Dish during the Open House, August 11, 2018

Editor’s note: During the DSES Open House on the weekend of August 11, 2018, three receiver systems were tested on the 60-foot dish antenna. Dr. Richard Russel reports on their successful results, and he shows what we see in our data plots. Some highlights to point out:

  1. The Spectracyber definitively observed the neutral hydrogen of the Milky Way as the beam width completely crossed the galactic plane.
  2. The RASDR4 observed a known neutral hydrogen radio source, which has a closer cloud along the line of sight that absorbs some of the hydrogen signal. The distinctive signal feature is known from published data by the Parkes Radio Observatory in Australia.
  3. The RASDR2 detected a 1296 MHz beacon set up at the home of a member about 80 miles away.  This is our first definitive detection of a beacon at 1296 MHz.

Open House Observations using the 60-foot Dish Antenna

The DSES and Society of Amateur Radio Astronomers (SARA) teams installed three different receivers onto the 60-foot dish during the open house.

 

Successful Installation and Testing of the DSES Spectracyber Neutral Hydrogen Receiver.

The Spectracyber was installed on the 60-foot dish during the DSES Open House on August 11, 2018.

The Spectracyber measures 1420.406 MHz +- 600 KHz. The observation was taken while passing the galactic plane at RA: 19hr 5 Min, Dec: 6 degrees 0 Min.

The observation shows a significant signal to noise ratio as seen below.

Follow-on observations will allow for measurement of the rotation rate of the Milky Way and Solar System!

 

RASDR4 Receiver Successful Observation of Hydrogen Absorption Line

Tony Bigbee used his RASDR4 on the 60-foot dish to observe this hydrogen absorption line at RA: 18.15hrs, Dec:-20 deg.

This target is a hydrogen source with a cloud of material between the source and Earth that absorbs the hydrogen energy resulting in a drop off of signal as shown below.

1296 MHz Beacon Observation using a RASDR2

Bogdan Vacaliuc installed a RASDR2 onto the 60-foot dish and was able to observe the 1296 MHZ beacon at Ray Uberecken’s house, about 80 statute miles distance to the west-northwest. This observation helped verify the azimuth pointing accuracy of the 60-foot dish.

 

Preliminary Baseline 420 MHZ Celestial Drift Scan Survey, December 2016

Here is my fist shot at a survey! A lot of things I can fix for next survey, planned for after Christmas.

1) Will have a 15dB preamp installed on mast
2) Will raise frequency to midrange of antenna sweet spot (435 MHz)
3) Will do a better alignment of antenna

This was fun!!!!!!

New Milky Way H Map – Incredible Detail

Sky & Telescope has a short, illustrated news item today about high resolution 1H (atomic hydrogen) observations of our galaxy from Australia and Germany. It includes a video showing how the view changes with wavelength due to Doppler shift. I thought this would be good to share; this is what we’ll be looking for with the HI drift scans.

Radio Jove and SuperSID Data and Analysis Reports

Attached are the August reports for the Radio Jove, located at Plishner, and the SuperSID, which is located at my house.

1) The Radio Jove observing season is closing down with only an hour of observing time a day after sunset. We did get a couple of probable hits.

2) SuperSID did detect an M1.3 flare on 8 August. I also conducted a comparison of the Radio Jove results and the SuperSID results. I found no significant correlation between the two telescopes. The lightning storms this month also affected both telescopes by adding a lot of spurious signals.

I have been in contact with the Radio Jove NASA coordinator. He likes what we are doing and has provided information to improve our Radio Jove system.

DSES Perseid Meteor Shower Open House

Deep Space Exploration Society

Perseid Meteor Shower Expedition 2016

DSES conducted its first open house on Friday, August 12, in conjunction with the Perseid Meteor Shower. We had 11 DSES members and over 20 guests spend the evening looking at Saturn, Jupiter, Mars and the Moon through telescopes while watching for meteors at the Plishner Radio Astronomy and Space Science Center in Haswell, CO.

We had five optical telescopes on site for viewing of the skies as well as lectures from 2 Pikes Peak Community College astronomy instructors who provided instruction on the use of the various telescopes present.

We had a few glitches such as the mice eating the wiring in the generator controller which shut down the main source of power for the site. However, thanks to some quick calls, Dave and Bill were able to get a generator shipped down to the site. This generator powered the site for the next two days while Ed worked out how to fix the primary generator regulator.

Special recognition for Don and Adam who traveled 4 hours to attend the event. They also spent many hours clearing the bunker ramp of tumbleweeds.

We had four or five optical telescopes set up for everyone’s viewing pleasure and some of the local community came out for an impromptu start party. Everyone had an educational and great social time together.

Kevin Ahrens and several other photographers came down and shot some amazing photos and time-laps videos of the storms rolling in.

AntennaComposite

Gary Agranat organized and manned a special events Ham station and collected 86 contacts on several different bands during the event.  This was the first major use of the DSES new Club Station call sign, k0prt (prt stands for Plishner Radio Telescope). New QSL card were made by Kammie Russel, the daughter of a DSES member.

Radio

Much progress was made in outfitting the dish and getting control set up.

RadioVan

Many members stayed overnight at Diane’s Park which is under the 60 foot dish.

Ray and Floyd prepared a 6 meter antenna for the meteor detection radio telescope. The communications van was outfitted with extra antennas for 6 meter ham radio plus UHF and VHF amateur satellite communications. The van also has a 6 meter to 180 meter dipole for HF communications.

AntennaFarm

Bob counted sunspots and solar prominences using the solar telescope lent to DSES for this event by Pikes Peak Community College. A star party with multiple optical telescopes was a big hit while watching for meteors.

OpticalTelescopes

Myron set up an AMSAT communications system in the communications van.

AMSAT

The neutral hydrogen experiment was installed using the SpectraCyber system. The dish was moved to accommodate the new advanced feed built by Ray. The feed will be permanently mounted on the dish in the next couple of week. This will allow for UHF, VHF, 1296 MHz Earth-Moon-Earth  (moon-bounce) and 1420 MHz neutral Hydrogen radio astronomy.

The next expedition will involve using the new antenna feed system for the ARRL Moon Bounce contest in the October time frame as well as the first use of the primary dish for the neutral hydrogen radio astronomy experiments.

Plishner Open House Weekend August 21, 2016

K0PRT20160814KL7YY6mSSBOpen-HouseCOrev1

I set up our eQSL account and created an eQSL card for us. I then uploaded our log file from our weekend QSOs. I attached an example of our eQSL that goes out to our contacts. (In this case it is to Myron, who gave me a call from his radio.) We had 86 QSOs. 9 eQSLs from the weekend were already waiting for us in the eQSL inbox.

I will attempt to set up an ARRL Logbook of the World account for us this week. And when I have a chance I will provide an update to Steve for the QRZ page, now that our weekend activity completed.

Also when I get a chance, I’ll email my photos from the weekend to Bill.

DSES Open House 8/12 & 13

DSES will conduct its first open house this weekend, Friday, August 12 and Saturday August 13, starting at 5 PM on Friday. The Perseids Meteor Shower event should be at its peak this weekend (after midnight) with an estimated 200 to 300 meteor’s per hour.

We should have several optical telescopes on site for viewing of the skies. We will have radio equipment on site for all our working science projects. A ham radio station using the new DSES club call sign K0PRT (Plishner Radio Telescope), will be on the air on several High Frequency radio bands. We also hope to have an amateur radio Oscar satellite station working as well. Our big project for this weekend will focus on installing the new tri-band dish feed. If all goes well with this installation we hope to bounce a 1.2 Ghz radio signal off the moon and be able to hear our echo 3 seconds later.

For those who may want to spend the night, please bring your own sleeping needs. We should have floor space in the bunker for your cot/bed. WE DO NOT recommend sleeping on the floor in the bunker at this time. We have lots of parking space for RV’s, trailers, or trucks/cars. We will start grilling hot dogs around 6PM Friday. Be prepared for hot temps during the day and thunderstorms, rain, wind and maybe hail during late afternoon or evening. Mud boots may be nice to have if it rains.

The Plishner site is located at 9301 County Road 20, Haswell, CO or 4.8 miles south of the town of Haswell, CO.

Call me if you need directions or further information on this weekend’s events. Hope to see you there!!
