HamSCI: Solar Eclipse QSO Party and Gladstone Signal Spotting Challenge

We are writing to you on a matter of scientific urgency.

HamSCI stands for Ham Radio Science Citizen Investigation. We have been actively engaged in scientific data collection for both the October 14, 2023, annular solar eclipse and the upcoming April 8, 2024, total eclipse. 

Two major activities that HamSCI will be involved around the solar events will be The Solar Eclipse QSO Party (SEQP) and the Gladstone Signal Spotting Challenge (GSSC) which are part of the HamSCI Festivals of Eclipse Ionospheric Science.  Other experiments that will also to be conducted include the Time Delay of Arrival (TDOA) experiment, the Very Low Frequency (VLF) Reception Exercise and the Medium Wave Recordings Event. Members of HamSCI, along with the amateur radio community, will be creating data for researchers by transmitting, receiving, and recording signals across the high frequency (HF) spectrum.  

We would like to encourage you to cooperate on a joint astronomy/radio outreach event for the upcoming eclipse. The event promises to be one of the science highlights of the decade. Many astronomy clubs are planning to host outreach events in their town or near the centerline of totality. However, seeing the eclipse visually might be clouded out by unpredictable April weather. 

But terrestrial weather is not space weather. At radio frequencies. amateur radio operators can still bounce their signals off the ionosphere high above the clouds to communicate with other hams hundreds or thousands of miles away. It is the Sun’s light which ionizes the upper air and produces the ionosphere, so during a solar eclipse the ionization lessens, and the ionosphere gets weaker, and its bottom level gets higher. This change can be observed with amateur radio equipment. At high frequencies a distant bounced signal fades, but at very low frequencies it strengthens as an absorbing layer weakens. With specialized equipment (go to www.hamsci.org/eclipse) you can even observe the changing Doppler shift as the bounce altitude recedes skyward then returns toward the ground as the Moon passes off the face of the Sun using the Grape 1 personal space weather system equipment). 

For ideas on eclipse activities visit the NASA/Arizona State University (https://scope.asu.edu/eclipse-activities/) and also the HamSCI (hamsci.org/eclipse) websites where you will be encouraged to join the solar eclipse QSO party (SEQP). 

Please let us know if you need any help. We hope you have a great eclipse experience and can send us a photo or a short report after the event.

Amateur Radio Operators Needed for Help with Solar Eclipse Project

From ARRL News:

The Case Amateur Radio Club, W8EDU, the club station at Case Western Reserve University in Cleveland, Ohio, is asking for amateur radio operators to help with a research project centered around the April 8, 2024, solar eclipse.

W8EDU club member Adam Goodman, W7OKE, said the project centers around studying the effects of the eclipse on propagation to better understand the recombination time of the ionosphere.  

“To do this, we are recruiting North American amateur stations interested in recording the Canadian time standard station CHU (Canada’s WWV) for two weeks surrounding the eclipse,” added Goodman. “Anyone with a KiwiSDR or a rig that can interface with analysis/recording software such as Fldigi is encouraged to reach out to us to participate.”  

W8EDU club member and project software manager Maris Usis, KE8TXG, said that while the software is simple to use, there is some detailed work involved. “We can help make it easier and there are good online instructions as well,” said Usis.  

All of the participation details are on the club’s website at https://w8edu.wordpress.com/chu-eclipse-data-collection/.  

W8EDU club faculty advisor David Kazdan, AD8Y, said the research project has received positive attention from the ARRL Collegiate Amateur Radio Program community, the Ham Radio Science Citizen Investigation (HamSCI) community, and Case Western Reserve University’s engineering deans. “It is already a truly international effort, and we are collaborating with more than 20 stations across the continent, from collegiate and high school stations, to a representative from the Radio Amateurs of Canada, to a station in Mexico,” said Kazdan.  

The 2024 solar eclipse will over Mexico, the United States, and Canada. ARRL is a partner with HamSCI to help promote this opportunity for radio amateurs to participate in an active science experiment, through the Solar Eclipse QSO Party.

The First Amateur Radio Station on the Moon, JS1YMG, is Now Transmitting

From ARRL News:

02/02/2024—The Japan Aerospace Exploration Agency (JAXA) successfully landed their Smart Lander for Investigating Moon (SLIM) on January 19, 2024. Just before touchdown, SLIM released two small lunar surface probes, LEV-1 and LEV-2.LEV-2 collects data while moving on the lunar surface, and LEV-1 receives the data.

The JAXA Ham Radio Club (JHRC), JQ1ZVI, secured amateur radio license JS1YMG for LEV-1, which has been transmitting Morse code on 437.41 MHz since January 19. The probe uses a 1 W UHF antenna with circular polarization and is transmitting “matters related to amateur business.”

Radio amateurs have been busy analyzing JS1YMG’s signal, with Daniel Estévez’s, EA4GPZ, blog introducing the method and extraction results for demodulating Morse code from the signal, as well as extracting the code string.

It’s unclear how long signals will be heard. JAXA has said that SLIM was not designed to survive a lunar night, which lasts about 14 days, and is due to return in a few days.

SLIM was launched on September 6, 2023, and landed on January 19, 2024, with the mission of analyzing the composition of rocks to aid research about the origin of the moon. SLIM’s landing made Japan the fifth country to achieve a soft touchdown on the moon. The landing was achieved with exceptional precision — within 180 feet of its targeted touchdown location.
