              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night was beautiful! It was clear pretty much the entire night except when some small clouds quickly rolled through during B half.  However, while it was clear, the atmosphere was turbulent so seeing was only good, not spectacular.
The Echelle stayed moth free but Tspec was bad. I took images all night but there was no improvement.  I rotated the instrument and removed the AUX cap at during dawn fills and I can see the temperature is coming down but the images continue to be corrupted.
