                ------------- ACTIVITY LOG --------------
 Observing Specialists: R.McMillan
 The night was mostly clear.  NICFPS and Echelle both got good seeing;
 APOLLO suffered some worse seeing due to a windshift a few minutes
 after midnight (and also to high airmass for the summertime moon).
 The telescope and instruments were generally well-behaved.  There
 was one crash of the echelle slitviewer which required a power
 cycle, but the telescope continued tracking nicely and we recovered
 before the exposure was over, so no time was lost.
 At the end of the night I stopped the echelle fill sequence and
 closed the nitrogen valves to the instrument in preparation for
 pumping.
