                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 At 22:30. guider image g0245 the guider started to loose track of the
 guidestar.  I noticed the guider was guiding, but switched over to
 manual mode instead of guide on star at g0303.  I don't recall much in
 the way of an audible warning of it switching to manual mode, and didn't
 notice the purple cross was missing until I happened to glance a little
 closer.
 At approx.  22:55 guiding failed, images g0326-g0332, again.  This time I
 was paying closer attention.  The audio file on Jeppe isn't obvious,
 sounded very similiar to another sound effect I had so I didn't notice
 it (I will change the sound effect to something more annoying (useful)!)
This I
 don't think is a bug, but not sure why it lost the guidestar.  I
 restarted the guider with a brighter star, although the star I was
 guiding on should have been fine 1100 cts above bkgnd.  It seemed to like
 the brighter (more bloated star better).
 Which of the controls do we adjust to increase the search radius for the
 star?
 My observer issued offsets (Object XY) at 23:15 and the guider adjusted
 to the new stars position correctly (as I expected and hoped).
 My user noted one thing she did not like in TUI (perhaps already
 addressed in TUI 1.2).  The UTC clock is based on the local machines
 clock and not APO UTC clock (or perhaps a .gov time server clock).
 No Problems tonight.
