                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Noel Camron Hastings
 2nd Half Observing Specialist: R.McMillan
 Most of tonight's work, both first and second half, was done in
 off-sky engineering, data analysis, and documentation work.  There
 was also a period of a few hours around midnight when the clouds were
 too thick to do anything even if we had opened.  I eventually opened
 the telescope late in the morning to obtain more data to check
 against my analysis of mirror stability.  I also planned to check out
 the new TCC version, but it turned out the update had not been
 implemented yet.
