Last week
  • Weatherstation issue - not reading wind data. LeRoy found the media converters in a bad state and one fiber broken. Rear is still not reading.
  • Transition meetings - ALH, OAC, AzCam, LBC, DIMM.
  • Wiki updates for OAC telemetry and new build dependencies.

  • PIT
    • Revisit PIT table and send a test release to science operations.
  • OT/LBC #7380
    • Possible issue with proper motion units/amounts in LBC scripts. As part of the investigation had to generate a spreadsheet with all the observations done since proper motion was added to the OT and grab the LBC XML generated. Also started to look a little bit into the LBC code to understand how proper motion is handle.

This Week:

  • Handover
  • PIT point release.
