...Shutter is open


Data on Arp 143 taken:
  • Working from obs2 /home/lbto/Service_Observing/Eng_Dec2019
  • Arp 143 collimation script was track mode. Olga fixed it from OT file (Coll.xml)
  • 0.73" from guider images & wfs

Heater appears to have blown circuit breaker on S wall of RemoteOps rm507-3 and rm507-4 (6-headed computers) lost power Plugged into another wall directly with extension cord Rebooted rm507-3

0072-0074 are junk - still taking data although configuring for transform

11:45 Configuring for L1 transform data collection. Changed LZP and stopped/started PCS.

Stone_E was too low, but Stone_I was OK. Decided on Stone_I_m93.list with FeII and exptime=4 since the on-axis star is bright. But while collimating, the preset was canceled. It looks like the AZ torques were railed. There is a problem with the AZ frame.

No useful data were taken for the L1 transform and AGw4 problems prevented even attempting the L2 transform confirmation.
