The Canadian CASSIOPE (CAScade, Smallsat, and Ionospheric Polar Explorer) spacecraft once again eavesdropped on ARRL Field Day activity. CASSIOPE’s Radio Receiver Instrument (RRI) was tuned to 7.005 MHz during six passes over the North American continent during Field Day 2018, although there was no advance publicity this year. The RRI is a component of the spacecraft’s Enhanced Polar Outflow Probe (e-POP), a suite of eight science instruments that study space weather.
“We’re really happy with our results this year,” remarked Gareth Perry, a physics and astronomy postdoctoral research associate at the University of Calgary in Canada, CASSIOPE’s home institution. “RRI recorded plenty of chatter between Field Day participants, especially during our passes over the eastern and central United States on the evening of [June 23].”
