Observing Specialist: C.Gray
I don't remember the last time Tspec was used so much! I'd forgotten how much that instrument can push up against dawn. We had a great night with clear skies and good seeing.  JH01 was kind enough to donate some of their time to JH06 so they could finish off a target. Everyone collected such good data!! And so much of it!
No problems tonight
