Abstract:
We collected several THEMIS observations of plasma sheet oscillations with kinetic ballooning/interchange instability (BICI) signatures. Using an adapted model to find the location of THEMIS footprints, we identified all-sky imager (ASI) observations that may be associated with the waves. The ASI observations reveal a reach activity often being diffuse patchy aurora. We investigate the brightness and motion of the auroral patches and compare them with the BICI activity in the plasma sheet.
