              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
At 21:00, Anjum messaged that her FOV was not matching up with her guider
charts. I did a pointing check, and this worked to put a star in the
guider. We confirmed her coordinates, and I got on the phone with Russet
for some advice. She slewed to another bright star from the APOLLO
catalog, and the pointing did not look right.
Changed the instrument from BLUE_DIS to DIS, and confirmed the pointing.
The bright star arreared on the slitviewer as it should. When this was
confirmed, we switched back to BLUE_DIS. The pointing seemed okay after
that. Anjum slewed back to her FOV with BLUE_DIS, and saw the correct
field. We are not sure what this problem is. There were no pointing
problems after this. This took half an hour.
Had to close at 03:45 because of 5500 dust counts. Tried to open again at
04:10, but inside counts shot to 5200, so I immediately closed again. Dust
levels did not go down until 05:32, when I opened again. We pushed with
dust between 4400~5800 inside the dome.
