Dynamics of ring current ions as obtained from IMAGE HENA and MENA ENA images 

Perez, JD; Zhang, XX; Brandt, PCS; Mitchell, DG; Jahn, JM; Pollock, CJ (2020-06-18)
Ion distributions from three storms in the year 2000 have been obtained from HENA and MENA ENA images at 27-39 keV and 5-12 keV, respectively. The observed motion of the ring current is compared with calculations of expected ...

Overlap of the plasmasphere and ring current: Relation to subauroral ionospheric heating 

Gurgiolo, C.; Sandel, BR; Perez, JD; Mitchell, DG; Pollock, CJ; Larsen, BA (2020-06-18)
The overlap of the ring current with the outer plasmasphere is thought to play a major role in storm-time related increases in the subauroral ambient topside electron temperature. Instabilities generated within the overlap ...

Trapped and precipitating protons in the inner magnetosphere as seen by IMAGE 

Perez, JD; Zhang, XX; Brandt, PC; Mitchell, DG; Jahn, JM; Pollock, CJ; Mende, SB (2020-06-18)
[1] Images from the IMAGE satellite of precipitating protons (SU12/FUV) and trapped protons at 8.5 (MENA) and 33 keV (HENA) are compared during three periods: ( 1) 12 August 2000 from 1000 UT to 1145 UT just after the peak ...
