Upcoming Activities

* *

At this time we are holding our monthly meetings as virtual meetings. Our engineering meetings are normally held on the second Monday of each month. Our science meetings are held on the fourth Monday of each month. Start time is 5:30 PM. Email notifications are sent to members prior to the meetings. If you would like information to participate, please contact us at information(at)dses.science.

Work trips to the Haswell antenna site are generally scheduled for each third Saturday of the month, with weather alternates on Sunday. This third weekend was chosen because it comes between our engineering and science meetings. Having a regular date helps our members plan ahead, especially those who must travel long distances. During the Covid-19 pandemic, work and science trips may be coordinated for other times. NOTE: Please coordinate with us before you go to the Plishner site, information(at)dses.science.

News

A DSES observing team were at the Plishner radio telescope site on Saturday September 12, 2020. The team successfully observed 3 new pulsars that we had not observed before: B1508+55, B1749-28, and B1933+16. We tried but did not detect 4 other pulsars. Members of the team were Rich Russel, Bob Haggart, Bill Miller, and Gary Agranat. 11 Pulsars Observed so far, as of 9-12-2020.

DSES Pulsar Observing Team netted 5 pulsars! The observing team of Rich Russel, Ray Uberecken and Glenn Davis observed 5 pulsars we had not detected before. The observations were done on Saturday September 5, 2020 with the 60-foot dish antenna at Haswell. After realigning the azimuth calibration, all observation runs were successfully. See the post and slides . Details to come at the next science meeting.

We posted the video and slide set from our DSES Science Meeting of August 24, 2020. The meeting was hosted by Rich Russel.

We are now posting on the Home Page our Planning Schedule for Observations and usage of the 60-foot antenna at the Plishner site in Haswell. Please coordinate usage at our engineering and science meetings, or contact the Science or Engineering Leads.

The Society of Amateur Radio Astronomers 2020 Annual Eastern Conference now has its presentation talks available online. [August 17, 2020]

The Society of Amateur Radio Astronomers 2020 Annual Conference was held online on August 1-2, 2020, and by all accounts it went well. Nominally the conference is held each year at the Green Bank Observatory in West Virginia. This year the conference was carried completely online using Zoom. And this year the coordinator for the conference was our own DSES Science Lead, Richard Russel. Over 93 SARA members participated, including several DSES members. DSES members Ray Uberecken, Skip Crilly, and Rich Russel gave talk presentations. Rich was also elected as Vice President of SARA. [August 8, 2020]

We are sad to report that DSES Member Mel Graves, WR0I from Sedgwick, KS north of Wichita became a silent key on August 6, 2020. Mel was a voting member of DSES for over 7 years and was very excited at what our 60 foot dish would offer to ham radio and the radio astronomy community. I first met Mel at the 2016 Microwave Update Conference in St Louis in 2016 and again in 2017 at the Central States VHF Conference in Albuquerque. Mel was very active on VHF, UHF, and Microwave across the Midwest and was recently accumulating 47GHz and 122 GHz equipment. Funeral arrangements are currently pending. [August 8, 2020]

Active Experiments

Current experiments now in progress at the Plishner Radio Astronomy & Space Science Center site in Haswell:

60-foot dish antenna:

Current main work with the 60-foot antenna is to develop our ability to detect pulsars. This includes being able to track (at this time manually tracking) on specific celestial coordinates. We succeeded in observing our first pulsar on May 2, 2020.

We are regularly using the 60 foot dish antenna for joint observing runs for SETI with Skip Crilly at the Green Bank Observatory in West Virginia. These joint observations are discussed in several of Skip's presentation slides. Please see our presentations page.

Jupiter Radio Science Experiment "Radio Jove":
20.1 MHz monitoring of Jupiter and its moon Io, using a 2-element phased dipole antenna - currently down, pending repair of the receiver.

Experiments in Colorado Springs:

Drift scan survey of Milky Way of HI 1420 MHz spectral line.

Development of hardware/software and techniques for detecting pulsars.

Sudden Ionospheric Disturbance Monitor (SID):
- 25 kHz VLF Solar flare monitoring
