1. Planning summary
===================
1.1 General remarks
a) JEM-X 1 and 2 on. Start of SPI annealing.
b) 2012-06-06T11:12: Pointing 17 missed.
c) 2012-06-07T04:49: Integral went in ESAM mode (see par. 6, Anomalies report).
Cause: SEU on the Reaction Wheel Drive Electronics of Wheel 4, this caused the wheel to
de-spin and the Satellite to rotate correspondingly until SAS-1A detected an anomalous
attitude and the onboard autonomy triggered.
2012-06-07T07:51: Start of recovery.
2012-06-08T00:39: End of recovery, timeline rejoined in PID 82.
d) 2012-06-08T09:08: update of slew 92 failed, pointings 92 to 94 missed.
1.2 Pointings summary
Remarks: Only Science Windows (ScWs) of type 'pointing' are considered.
- Exposures info from POD version 2. Pointings info from TSF version 5.
- Durations in exec/planned format; data gaps and bad time intervals not excluded from total time.

expected deviations (first & last pointings of an exposure longer than planned) not reported.

6. Anomalies report:
====================
First e-mail from Richard Southworth, MOC from 2012-06-07T12:36:
------------------------------------------
"Integral entered Emergency Sun Acquisition Mode (ESAM) this morning at 04.49z.
The cause of the ESAM entry was an SEU on the Reaction Wheel Drive Electronics of Wheel 4,
this caused the wheel to de-spin and the Satellite to rotate correspondingly until SAS-1A
detected an anomalous attitude and the onboard autonomy triggered.
The ESAM entry triggered and executed correctly, following ESAM entry all statuses were
as expected including the payload units safe mode selection.
Within 8 minutes of ESAM triggering the Satellite was in a safe controlled attitude with
SAA close to 90DEG.
The Reaction Wheel Drive Electronics 4 health has been verified as it was switched on almost
immediately after the switch off (although this was too late to prevent ESAM entry), the
power consumption of the unit was nominal indicating that the LCL was not switched off due
to over-current.. This means that the ESAM recovery should be relatively straightforward
involving no onboard configuration changes.
The recovery started at 07.51Z following arrival of the appropriate engineering and FD support
and thorough checkout of the Satellite status. The recovery to rejoin nominal TL operations
is expected to take in the order of 12 hours provided no complications arise."
2nd e-mail from 2012-06-08T00:31:
---------------------------------
"The recovery from this morning's emergency mode entry is almost complete, Integral is back in
the nominal AOCS pointing mode and all instruments have been recovered. The remaining
operations are 2 Open Loop Slews, a Reaction Wheel Bias and a closed Loop Slew to recover the
planned attitude, we expect to be able to rejoin the automated timeline within the next 2 hours."
