                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Opened around 17:00 to begin cooling.  There was cirrus spread evenly
 around the sky which persisted after sunset.  I spent the early part of
 the evening training the on-site observers in the use of Remark and the
 SPICam interface and we did get a small amount of data.  The quality
 isn't good but it was a useful exercise for Bertrand to become familiar
 with using the instrument.
 2nd Half Observing Specialist: J.Dembicky
 Pesky clouds all night long but some data was obtained thru them.  Clouds
 finally became too thick around 04:10 and nothing useful was obtained
 after that point.
