2017 Total Solar Eclipse

On 21 August 2017, a total solar eclipse caused the shadow of the moon to traverse the United States from Oregon to South Carolina in just over 90 minutes. Although the ionospheric effects of solar eclipses have been studied for over 50 years, many unanswered questions remain. HamSCI invited ...

Personal Space Weather Station

PSWS Overview ThePersonal Space Weather Station project ultimately aims to create a small, multi-instrument system that can make ground-based measurements of the space environment.  The observations from this project will not only be useful to the owner of the system, but also aggregated into a...

Swarm-E (formerly known as e-POP)

In the spirit of making data from the Radio Receiver Instrument (RRI) onboard Swarm-E (formally known as e-POP) more accessible to the ham radio community, we have converted RRI's data into a ".raw" format so that it can be ingested into open source software such as Gqrx or GNU Radio.  We have done...

Amateur Radio Response to Solar Flares and Geomagnetic Storms

Summary Solar flares and geomagnetic storms can significantly impact the ability to commicute on the medium and high frequency (300 kHz - 30 MHz bands). Solar flares cause radio blackouts due to collisional absorption from enhanced D-region ionization, especially on the lower frequencies....
