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.

This autumn Dr. Richard Russel attended the Very Large Array (VLA) Imaging course in Socorro, New Mexico. The course taught how to take the data sets from multiple large interferometer antenna systems and produce images and science statistics.. This post presents the slides from the DSES Science Meeting on November 25, 2019. This is an update from Dr. Russel’s posts on the topic from October 19 and 31.
Dr. Russel also presents his September 2019 results of Hydrogen 21 cm (HI) drift scan measurements at his newly installed 9-foot dish antenna at his home in Colorado Springs.

Recently Dr. Richard Russel attended the Very Large Array (VLA) Imaging course in Socorro, New Mexico. This course taught how to take the data sets from the VLA archive and produce images. The following is the first set of images reduced from the VLA archive by Dr. Russel.
Images were made of these astronomical objects:
- 3C75 Binary Black Hole System
- 3C391 Supernova Remnant
- Asymptotic Giant Branch (AGB) Star IRC+10216
- MG0414+0534 Gravitational Lens HI Absorption Line
Each image takes about 1 day to produce from the raw observation.
Dr. Richard Russel put together this slide set about the latest results from this month’s observing. Contents:
- Galactic Rotation Rate Results
- Earth’s Position in Solar System
- Complete HI spectrum Measurements from all observing trips
Dr. Russel is now utilizing Doppler shift measurements, and hence velocity, to also estimate the Earth’s position in the Solar System.

DSES President Dr. Richard Russel has been measuring signal strengths 0f stations in the Very Low Frequency (VLF) band for the past year, looking for changes in ionospheric propagation due to solar flares. He uses a Sudden Ionospheric Disturbance (SID) monitor small radio telescope. His SID detector is located in Colorado Springs, CO. The measurements are sensitive to the changes in radio propagation at sunrise and sunset.
With his baseline of historical data at sunrise and sunset, he then predicted what could be expected during the August 20, 2017 solar eclipse. He presented his prediction work at the 2017 Society of Amateur Radio Astronomers Annual Conference at NRAO Greenbank, WV on July 25, 2017. His paper was titled, “Ionospheric Reflection Variation During Sunrise and Sunset and Predictions for the 2017 Total Eclipse”.
During the eclipse he made measurements, and found the results matched closely with his predictions. The link presents a summary of his work. Plus it has YouTube links to this and another of his talks at the SARA conference. The second talk is titled, “The Use of Monte-Carlo Analysis to Evaluate Radio Astronomy Source Detection”.
