  • 800 counts. Strange behavior, looks like shutter got stuck. Test with V and r fast OBs.
  • Shutter seems not to be working. Try shutdown and restarting the camera.

02:00 - No way. Shutter in strange position
  • Try to move with testpower and minicom.
  • Succeeded.

02:20 - Exposure ok. Restart (35 min downtime, although it does not affect science time, as it happened during twilight)
