                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 AZ Vel Scale was 580.0  Measured 574.1  No Change Made
 I found a pecularity with the DIS expose window.  My display doesnt
 match the users.  Maybe this has been there all along?   The user had
 only the blue camera only selected and my display showed both blue and
 red selected.
 A 480s dis expoure (blue only) was aborted and the subsequernt blue
 images were blank.  I took an images from the APO account and things
 looked fine.  Gave the instrument back to the observer and it worked
 fine.  No real time was lose we were closed due to weather.  I really
 don't know what happened or what I did that fixed it.
 I tweaked DIS focus on the fly.  We started at 1.4 arc sec and by 22:00
 we were at about 1.0 arc sec.
