ROSAT Status Report #17

Satellite and Instrument Status

The synchronization problem of the HRI instrument has apparently been solved by the new command procedure, which invokes a reset command timetagged after every belt or SAA passage. During the last observing period (December 6 to 11) no further telemetry turmoils have been noticed.
