1. Planning summary
===================
1.1 General remarks
a) 2023-01-04T20:47: IREM crash.
b) 2023-01-04T20:54: IREM crash.
c) Unexpected transition to belt configuration for the instruments.
On DOY006 at 02:55Z, there was an unexpected transition to belt configuration for the instruments due to
a human error (typo in belt entry time) during the recovery of the IREM crash on DOY 004.
The sequence of events was as follows in this rev 2591:
DOY004:
19:57 IREM crash
20:11 One digit incorrectly entered in manual recovery of ED DEBPG100 -> Belt entry was set to 006.02.55
instead of 006.22.55
DOY006:
02:55 (incorrect) belt entry time -> instruments to belt configuration -> stop of observations
04:56 manual uplink of right belt entry time -> OMC went to standby
05:05 OMC went to NOMINAL by itself at the start of the pointing -> OMC was observing again at that point
07:01 IBIS recovery completed -> IBIS to science
07:35 JEM-X1 recovery completed -> JEM-X1 to science
07:59 JEM-X2 recovery completed -> JEM-X2 to science
SPI also was in belt configuration and returned to nominal science operation at 04:56
d) Numerous alerts 605 related to instruments: IBIS, JEM-X 1, JEM-X 2, OMC.
