                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
 Clear skies, hazy basin at sunset. We were able to get focused very soon
 after 12 degree twilight and had surprisingly good seeing for that time of
 night ~1.0". Good seeing all the rest of 1st half.
 2nd Half Observing Specialist: R.McMillan
 Second half was as smooth as a very smooth thing.  Except for one
 point where there was a sudden jump of a couple arcseconds (don't
 know why, it wasn't windy -- happened between dcam images 376 and
 378), which was too large for the guider to cope with.  But I got
 the star back in a couple of minutes.  Thin clouds later in the
 morning, in combination with the moon, did make photon collection a
 little chancy.
