Glenn Davis and Dan Layne made observations for pulsars at our Haswell antenna site this week, on Tuesday November 1, 2022. They successfully observed for the first time pulsar B1556 -44, making this the 23rd pulsar DSES has observed to date.
The PDF files in this post are their observation and data report, and an updated list of pulsars detected by DSES to date.
We had our May DSES Science Meeting over Zoom. The meeting was led by Rich Russel, our DSES Science Lead. These are his presentation slides of the meeting. (The meeting was hosted and coordinated by Floyd Glick and Bill Miller.)
We had 10 participants for this meeting. Some DSES business, work updates, and observing operations was discussed prior to the Science presenation part of the meeting.
Rich’s topic question for the evening was, why did the Event Horizon radio telescope group, who succeeded in 2019 to image a black hole for the first time, chose to observe the supermassive black hole in the active galaxy M87? To figure this out, we learned about what determines the physical size of a black hole, and its observable characteristics. And we learned about what determines the apparent angular resolution of an object in radio astronomy.
The meeting was recorded as a video mp4 file. We’re trying to transition to a new setup with Zoom. You can access the video of the meeting with this link. You can watch the first hour online. However, you can watch the whole meeting by going to the link and then downloading the video. You can then watch it as a video mp4 file.

Have Larsen Hess is a new member from Fairbanks on Myron’s list.
Myron is in contact with Larry Ludlow of the Fairbanks Gilmore NOAA tracking center employee and the deputy director of Mars Rover missions at JPL and another JPL employee and will try to get them connected with the DSES.
BOD nominations were made, the election was held, but only 11 ballots were returned and received.
Election results and officer assignments will be made by the new board at the all members virtual meeting which we agreed to schedule on April 12th in lieu of the normal engineering and ops meeting . Bill will organize and send an invitation to all members.
Virtual Open House Presentation a. Front Range 6 Meter Group. President, Paul Sobon sobonpaul(at)gmail.com asked for a DSES presentation on Wed., Feb 10th at 7PM. Please view Bill’s presentation of the “Virtual DSES Open House” recorded from the Front Range 6 Meter Group at http://dses.science/dses-presentation-to-the-front-range-6-meter-group. This prompted invitations to give the presentation to several other amateur groups. b. Bill and Myron gave the virtual live Open House presentation to the Artic Amateur Radio Group based in Fairbanks on March 12th c. Bill was invited and gave the Open house presentation to the Utah DX Amateur group on March 17th to about 28 members. d. Bill was also invited and gave the presentation to the Oregon Tualatin Valley Amateur Radio Club on March 18th to about 38 Members.
The ARRL has published the results from the 2020 EME moon bounce contest last autumn, which we participated in. Gary wrote a short post on the website about this, with links to further information. a. Gary mentioned last month, we were contacted last month by Rick Rosen K1DS, who was writing an article for QST about the contest. He included a segment in the article just about us. Gary attached the article that is now being published and attached the certificate we were awarded. b. In the post Gary explained a little how the scoring worked. We were credited with contacting 36 unique stations, which gave us a score of 90,000. And that put us in 4th place in the Multi-operator, all-mode, 1.2 GHz category. c. The Stanford University station W6YX, which we contacted, placed highest in our category, with 113 contacts. The highest number of contacts in the contest results was by a single-operator Eastern Russian station with 388 contacts, over several bands and modes. Gary suspects there is a higher density of EME stations in Europe, which can enable this kind of performance. d. Our operators for the contest were AA0L, KL7YY, and WA2JQZ. Glen Davis also was crucial for adjusting our antenna pointing system and ensuring we were operational. (WD0CUJ and Michael Namieka and Bill Miller KC0FHN also came out, and made a moon bounce test transmission, but didn’t make contest contacts.) e. The post on our website includes the Certificate and the QST article. ARRL 2020 EME Contest Results – Deep Space Exploration Society (dses.science)
Our Site is photogenic! a. Don Savage and Jason Fazio did an all-nighter at the site on March 17th. They would like to do an onsite class in night photography at the site need to work this through the board. b. Andrew Miller, another photographer based out of Denver would like to do a project on the site c. Marc Slover and Michael Rice compiled the time-lapse videos. https://www.youtube.com/watch?app=desktop&v=HLrpsVmBchE&feature=youtu.be
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 accomplishments and can replicate them at will, we should look ahead and decide what we do next. Everyone should think of a radio astronomy or organization project that they think would be doable and important and get those into a list that we can review and go after with some more detailed plans. The main categories of interest would be: a. New observation initiatives b. Ham Radio capabilities, contesting and special events c. On site open house for Aug 2021 d. Continued Infrastructure upgrade and maintenance. e. Instrument and electronics upgrade and additions. f. Scientific discovery, theory testing, and publication. g. Educational programs and events for members and students. h. Public outreach and member recruitment
There is an upcoming Schriever STEM Day on April 23rd from 2:00 pm to 6:00 pm. This may be an opportunity to gain some new members and is an excellent outreach opportunity if we can get an invitation. Gary will check into it to see if we can get an invitation.
Rich Russel will have a poster presentation this coming Saturday, March 21, 2021 at HamSci – Ham Radio Science Citizen Investigation .
Rich will present his work about predicting the signal response of the 2017 total solar eclipse using the SID (Sudden Ionospheric Disturbance) radio telescope. The SID detects changes in ionospheric propagation of VLF signals due to solar activity. SID also measures changes at nominal sunrise and sunsets. Utilizing his historical data and geometry, Rich was able to predict what happened during the eclipse.
Please follow the links to read Rich’s poster presentation and to learn more.

On Saturday Feb, 20 Gary and Bill gave the 6 science fair award certificates and checks to Carol Bach, the fair coordinator at UCCS, for distribution to the students.
If anyone wants to see the projects, Bill has a list and files
Call for BOD Nominations. We need at least three nominations for the board to replace or retain BOD members, Floyd Glick, Dave Molter, and Bill Miller by Feb 3rd. Bill called Dave Molter this week and he declined to be nominated for retention as he is too busy to serve. Don Latham was nominated and seconded in the engineering meeting and Ray Uberecken and Floyd Glick were also seconded in the meeting. Later Bill self-nominated and Myron seconded.
Bill moves that nominations after this meeting will close and he will send out the election ballots in Email. This was seconded and Bill will send out the Ballots on Feb 23.
