              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds for most of the 1st half but it cleared (well except to the west) and we were able to open a little after midnight.
Something was wonky with the Echelle IOL images at the end of the night.  I took a 2nd set to see if the problem resolved itself.  The red image looked saturated on the bottom, the blue and comp looked fainter and with an elevated background.   The second set looked better but the background was still higher.  The nurse tank looked about normal for the amount that should have been used.  It looks like the autofill for the CCD Reservour failed.  I force filled the echelle (the autofill worked for the shield but was not autofilling the CCD) and then manually filled the CCD side when I saw the autofill was not working.  Notes sent to Engineering staff and PR submitted.
No telescope problems tonight.
