A news bulletin issued by the National Association for Amateur Radio (ARRL) describes an experiment spearheaded by Virginia Tech students led by PhD candidate Nathaniel Frissell to detect transmissions from Ham radio stations with the Enhanced Polar Outflow Probe (ePOP) Radio Receiver Instrument (RRI) on-board the CASSIOPE satellite. A total of 23 stations, mostly in mid-western states, were detected during an ARRL Field Day on June 28. The reception of signals at 7 MHz but not 3.5 MHz was explained on the basis of ionospheric density levels measured by an ionsonde located at the Millstone Hill Observatory in Massachusetts. The operation of the ePOP instrument is managed by Dr. Gareth Perry at the University of Calgary. Read the ARRL bulletin at

Total Solar Eclipse took place on March 20, 2015
Effects of the eclipse on the ionosphere were observed by SuperDARN radars. The track of totality is shown.

Welcome to SuperDARN!
SuperDARN stands for Super Dual Auroral Radar Network. The network consists of more than 30 low-power HF radars that look into Earth's upper atmosphere beginning at mid-latitudes and extending into the polar regions. The radars operate continuously and observe the motion of charged particles (plasma) in the ionosphere and other effects that provide scientists with information on Earth's space environment. The knowledge gained from this work provides insight into space weather hazards including radiation exposure for high-altitude travelers and disruptions to communication networks, navigation systems (GPS), and electrical power grids.
The SuperDARN Research Group at Virginia Tech (VT) collaborates with an international community of scientists and engineers to operate radars and share data. The VT Group operates five radars. For a summary of the radars and their affiliations, visit the Radar Maps/Tables/Links web page.
