                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I ran the NICFPS focus script tonight.  The first attempt almost looked
 like it was going to work.  It actually found the FWHM for the first
 image, the second image it couldn't find the star to centroid.  I changed
 the centroid radius from 50 to 10, and then it couldn't find the star in
 the first image.  The star used had about 15000 cts when viewed with
 IRAF, so it should have been bright enough and not saturated.
 I changed back to Centroid radius of 50 and it couldn't find the star.
 Then I examined the image and put in corrected coords, it move just
 slightly.  I bumped the centroid radius up to 100 and it seemed much
 happier suddenly, well for the first 3 images, then if faild to find the
 star again.  Arghhh...  The star was starting to go into saturation.
 I tried a fainter star next (10k cts near focus).  This one almost worked
 (got 4 images before it couldn't find the star).  I tried another star
 and still no dice.  It might give 3 or 4 images before it can't find the
 star.
 No problems tonight with the telescope or instruments.
