Excellent transparency and good seeing. Target is still somewhat faint.Not doing an all night run because the target is days away from peak.

Note there is a break in the middle of this run, but all the images are uploaded in the same zip file because nothing was changed, and the telescope was not moved. (We were doing some camera tests for a while.)

Conditions tonight are very marginal. There is some high cloud tied to a very slowly moving weather system. Unfortunately we are right on the edge, and it could go either way at any time during the night. The seeing is also very poor, which is not helping image quality. The worst images have already been removed. On the other hand, Michelle was on-site and taking images as early as 0630 UT. This means the data does span a considerable amount of time, even if it is at sporadic intervals. Guy gave up shortly before 1300 UT.
