  • Transfer code works. The images are written to the internal disk and then transferred to the external disk.
  • Sources are consistent through 22:45 Chile time
  • The camera is moving to the left with a rate of 2 pixels for 500 frames, this was 488
  • Actually no turning left, the images started moving right, this is 1276
  • We may see huge differential image motion. Or it may cancel out in the COM frame.
  • We were taking 5 second exposures, from 11 until 322.
  • Started 1, 10, 30  second exposures with 323
  • Started 1, 5, 10, 30 second exposures with 326
  •  Frame 2110, still all sources detected.
  • Time 23:33, rotating the dome and taking pictures with the best exposure. Planning to take an additional hour of data after this.
  • 23:48 dome opened up more in addition to rotation.
  • 23:50, tried 3072, focus gone, going to run back.

  • Went up to dome and refocused. New data is in observe-readjust folder
  • We find decent sources but it looks like we have a significant shift to left. This time for real.
  • Will start taking flats at 1AM.
  • The files locations got fixed again. No left shift.

Stubbs comments- 

This looks like great progress, bravo. We need to be sure the cables and other elements are not trip hazards, and so I suggest running them under the grating floor somebow. Also the camera isn't pointed quite in the direction I was expecting but I'm sure you guys have that figured out. Finally, we need to be sure we aren't obstructing the new in-dome illumination system that Patrick and Parker are installing. 
Happy to arrange a time to talk over zoom tomorrow if you like.
