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

Perez, J; Zhang, X; Brandt, P; Mitchell, D; Jahn, J; Pollock, C; 0000-0002-4644-0306; 0000-0003-1960-2119 (2022-10-27)
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 ...

Statistical correlation of low-altitude ENA emissions with geomagnetic activity from IMAGE/MENA observations 

Mackler, D; Jahn, J; Perez, J; Pollock, C; Valek, P; 0000-0002-2318-8750 (2022-12-02)
Plasma sheet particles transported Earthward during times of active magnetospheric convection can interact with exospheric/thermospheric neutrals through charge exchange. The resulting Energetic Neutral Atoms (ENAs) are ...

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

Perez, J; Zhang, X; Brandt, P; Mitchell, D; Jahn, J; Pollock, C; Mende, S; 0000-0003-1960-2119; 0000-0002-4644-0306 (2022-12-02)
[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 ...
