              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Checked DIS bay 2 grating wavecenters today.  They looked fine although the instrument wasn't dis-mounted today but it was un-mounted last night for a brief period.
We had two instances of the TSPEC dither script just stopping tonight during a sequence.  Once at the end of 3 of 4 exposures, and a second time at the end of 2 of 4.  There may have been a problem with their connection, they had to re-log into TUI when this occured.
TSPEC didn't like keeping the guidestar when it moved back to the A position after a nod with a few faint stars tonight.  Using a brighter star helped but several times we only had faint ones to guide with.  The rotator didn't look far off from the tape marks this morning when I took the instrument off.
