Thanks, Eric. That means the spacecraft is nominal after yesterday’s short (~1 hour) eclipse which occurred between the two perigee contacts.



The perigee contacts were nominal for CMD and TLM. The Inertial maneuver was successful and battery balancing was nominal.
The following was completed:
               SSR Dump
               Reset Master Timer
               CAR #1015 ATS Upload – IBEX_2019_014_o0434a_v001.scr
               Reset FDC Totals
