All,

The perigee passes were nominal for CMD & TLM. The Inertial maneuver was successful.

For this orbit we had 2 star tracker resets. The first was on DOY 218/07:41:58 (Razor Issue I100-657) and the second was on DOY 224/11:19:51 (Razor Issue I100-658).

Both times the star tracker recovered normally and CAR 344 was used to reset the error flags.

The following was completed:

Reset the master Timer

SSR Dump -> Dump New

Dump FCBO buffer

CAR # 1053 ATS upload - IBEX_2019_233_o0458a_V001 91 Cmds

Set SC Time
