429105:30-05:3300:03performed some testing and found that when tracker starts it performs a correct for structure correction which could take as much as 3-6 minutes. At times it is very quick and not noticeable. If track is started with a specified AZ then correction is much fasternone... will wait to see if this can be programmed out or shortened.
140205:46-05:5000:04haven't seen this one in a while but it occurred once again. SAMS was not moving primary; noticed mode had changed to NaN; NaN which meant SAMS server was no longer updating or actively moving the primary.shutdown the sams sever and then restarted after a few minutes.
429508:38-08:4000:02trajectory stopped before end of track; according to tcs had at least 10 more minutes until end of track; trajectory self aborted before that was reacheddoing testing on guide probes so gathering data; had to abort and move on to another target.

Ops Commentsnone


TO Commentslong night with some commissioning goals accomplished; able to successfully guide on guide probes and guide cameras.


RA CommentsAt the beginning of the night we worked through a few software problems with the guide probes but in the end we got it all worked out and we are now guiding on either probe at any position. We also took some tracks for the DMI mount model.
