1. Planning summary
===================
1.1 General remarks
-------------------
a) Eclipse season. JEM-X 1 and 2 on.
b) Due to a further solar flare, JEM- X and OMC autonomously went to safe mode at
the following times:
2011-08-09 08:36: OEM:JEMX1 PROB DFEE1 (JEMX1 to SAFE due to high radiation)
2011-08-09 08:39: OEM:JEMX2 PROB DFEE1 (JEMX2 to SAFE due to high radiation)
2011-08-09 08:43: OEM: TO SAFE (OMC to SAFE due to high radiation)
Affected pointings: 14 to 26
c) 2011-08-09: JEM-X and OMC returned to nominal operations, sequence of events
was as follows:
2011-08-09 15:19:00 OMC enabled in t/l
2011-08-09 15:26:00 OMC goes to safe?, - probably re-enabled too early
2011-08-09 16:44:00 Both JEM-X1 and JEM-X2 in data taking
2011-08-09 16:47:00 OMC enabled
2011-08-09 18:32:00 OMC goes to safe again,s/s is disabled
2011-08-09 20:54:00 S/S OMC enabled on T/L
d) 2011-08-10T03:32: AIMU went on, pointing 34 shorter, pointings 35 to 39 lost.
e) 2011-08-11T10:24: SPI PSD Channel Rates went OOL Alarm hard Low, with value 0.
They did not recover of their own therefore following procedures were
performed in order to recover:
- SPI was commanded to CONF mode (FCP_SPI1_0160) and then returned to Photon
mode (FCP_SPI1_0130). However this did not fix the problem.
- Afterwards a PSD reset was performed using CRP_SPI1_3030, which returned
the PSD Channel Rates to nominal.
1.2 Pointings summary
--------------------
Remarks: Only Science Windows (ScWs) of type 'pointing' are considered.
- Exposures info from POD version . Pointings info from TSF version .
- Durations given in the executed/planned format; data gaps and bad time
intervals not excluded from total durations.
- Deviations: only unexpected deviations >30 secs for pointings assigned to
an exposure are reported; expected deviations (first & last pointings of
an exposure longer than planned) not reported.
