6627	10:45-10:50, 11:35-11:40	00:10	Dust spikes.
6651	10:51-10:52	00:01	Guider/WFS Probes Too Close to Observe Science Target Q# 2975	Aborted target.

TO Comments	Ran without DMI. Effects of no DMI are not being able to do accurate GRoC corrections. So long as the temps stay near the temp of the last stack with a working DMI, that can be tolerable. But, it seems if the temps change too much without accurate GRoC we won't get an accurate stack and thereby bad IQ on sky and during HEFI measurements (see ee50 for last stack entry tonight, it should be below 0.6 with good dome/atmospheric seeing). Otherwise clear all night.
