2240 Canceled 3C 273 capture to change focus to 2618.1

2245 Started capture of 3C 273

0218 Slewed and started capture of 3C 273

0335 Slewed and started capture of HD 103646

0348 Slewed to and started capture of WD1336+123

0510 Slewed to PG 1633+099

0511 Received Sharpcap error: “Error loading profile: The capture profile could not be loaded correctly. The problems were: Setting ZWO EFW to filter 3”. This filter position holds the r-filter that we need for PICSI-2 observations. There may be something wrong with the filter wheel, keeping it from changing to filter wheel position 3. A photo of the error is in the discord thread for this session

0513 Went into the dome and reseated the cables to the filter wheel - continued to get the same error message. Made the executive decision to close up for the night on account of this being a new error - we did not want to mess with the instrument/filter wheel and potentially damage something.

0520 Beginning shutdown procedure

0537 Completed shutdown, locking up

  • The north mirror door stalled for a second - we needed to open and close them a second time before all 4 closed
  • Sharpcap error showed unprompted, we were about to begin the capture for PG 1633+099 when it popped up
