Summary

Lost to weather, clouds at first and then snow.

Preparations

Armed with some new knowledge from Torsten about the startAcquire command, we were able to run acquire movies from both AGW3 and AGW4 and verify that GCS now displays both movies correctly.

Wayne had to restart oacserver on lbtmu107 to get AGW4 to talk to us.

Details

Not snowing, but heavy clouds and 99% humidty at sunset.

After some messing around with rotators and such........

Problem with new OSS

01:30 Closed-dome preset to M5_0050 fails
Dec 31 01:31:05.440 2009 Preset alert for left IRTC mode GUIDE: Invalid buffer: RPCERROR

Called Paul. He figured out that this was a command name problem in the new version of OSS because nobody had started the patched IIF-OSS client.

01:42 Started IIF and restarted OSS.

01:43 pointto M5_0050 gs=0 TelM="GUIDE"
Thu Dec 31 01:43:22.568 2009 Preset alert for left IRTC mode GUIDE: PCS reports MCSPU error returned - ERROR - Rot. disabled: State = HOLDING, TRACKING or WAIT_FOR_NEW_TARGET

01:50 pointto M5_0050 gs=0 TelM="GUIDE" - still had a rotator problem.

Restart PSFL because it also needs the new OSS-client.

01:51 pointto M5_0050 gs=0 TelM="GUIDE"
Thu Dec 31 01:51:25.742 2009 Preset alert for left IRTC mode GUIDE: Invalid buffer: RPCERROR
Paul messes with OSS some more.

01:54 pointto M5_0050 gs=0 TelM="GUIDE"
Thu Dec 31 01:54:39.048 2009 Preset alert for left IRTC mode GUIDE: Invalid buffer: RPCERROR
To quote Paul "How can this possibly be wrong?"

Restart PSFL again.

01:56 pointto M5_0050 gs=0 TelM="GUIDE"

Paul is rolling back OSS to earlier version. Restarting OSS/IIF/PSF.

02:00 pointto M5_0050 gs=0 TelM="GUIDE"

Night is lost to observing

03:30 It is snowing hard outside. I've sold the rest of the night to Doug O. to pump on LBC-Red in exchange for an elk steak. I definitely got the best of this deal. The main risk is that it was nearly snowing too hard to cook the steak on the grill.

06:27 took a dome flat exposure it verify that the AGW4 guide CCD is still working. No problems.
