              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Checkout images of tspec were corrupted.  I then unmounted from the telescope, and started the night with DIS.  By the time I started darks at 11 pm, it had fixed itself.
Started the night with thin clouds, but they quickly became problematic.  A large portion of the time IH01 was on sky, there was no data taken.  Radar returns eventually closed us, and we never opened again.
