e-POP's Measurements of the Topside Ionosphere's Response to the 2017 Solar Eclipse

Summary form only. We present measurements the Enhanced Polar Outflow Probe (e-POP) onboard the CAScade, Smallsat and IOnospheric Polar Explorer (CASSIOPE) performed during the August 21, 2017 eclipse. CASSIOPE transited across the path of totality of the eclipse within 10 minutes after totality over Idaho. The spacecraft was moving along a north-south track at an altitude of approximately 650 km. In this presentation, we outline results from 2 of e-POP's 8 instruments: the Radio Receiver Instrument (RRI), and the GPS Attitude, Position and profiling experiment – Occultation (GAP-O) instrument.
