                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Opened again arounf 19:40 to cool; the weather was much more promising
than last night at this hour.  Scattered storms over the mountains earlier
in the afternoon seemed to have fallen apart and the sky was gradually
clearing toward sunset.  Skies continued to clear toward the middle of
first half and remained clear for the rest of the night.  Dust counts
edged up along the limits all night long but were not high enough to cause
me to close.  Other than having problems getting the Echelle autoguider to
guide on 15th magnitude supernovae, all went without a hitch tonight.
