 1. Planning summary
 ===================

 1.1 General remarks 

 a) Pointings 50, 51 and 52 were affected by the spacecraft star tracker selecting
    a non-catalogue object as guide-star.

 1.2 Pointings summary

   Remarks: Exposure info from POD. Pointing info from TSF. 
 - Durations in exec/planned format; data gaps and bad time intervals not excluded from total time.
 - Deviations: only unexpected deviations >30 secs for pointings assigned to an exposure reported;
   expected deviations (first & last pointings of an exposure longer than planned) not reported.

 3. Alerts 
 =========

 3.1 All alerts except OOLs and missing scientific data

   * Level 2:

2002 At least one HK (configuration) parameter changed unexpectedly
     Program / version that has created this alert:  osm_const_param 1.0.1
     ScW: 268900380010

 3.2 Parameter out of limits 
 
     IBIS:
     -----
     Due to Solar minimum, the IBIS veto limits are not appropriate
     resulting in too many alerts
