English Abstract:
On July 28, 2014 at 00:48:14 the Canadian ePOP and DSMP F17 satellites were in near magnetic conjunction over a weak arc feature in the southern polar cap. They were near the same altitude (DSMP: 876km ePOP:1175 km). The precipitating electron flux estimated at DMSP was ~2 ergs/s-cm2) almost all of it coming from electrons with energies significantly greater than 100 eV. The Suprathermal Electron Imager (SEI) on ePOP observed a weak precipitating flux of low energy ( less than 100 eV) electrons associated with a field aligned current system observed on both satellites. Here we present detailed observations and compare them with calculations made using the Field aligned interhemispheric plasma (FLIP) code.
