                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Mostly clear with haze for most of the night and a little cirrus near
 midnight, good seeing for science and poor seeing later for
 engineering when it was non-critical.  Two science programs got data
 during first half (one for a sinking target and one as makeup for
 observations messed up earlier by an observatory mistake), and three
 and a half engineering tasks got done second half (DIS throughput,
 Echelle rotation, SH measurement, and confirmation of offset
 directions for SPIcam and DIS).
 Problems included another manifestation of the NMSU firewall problem
 (I ran the slitviewer for the remote observer), a dead ethernet card
 for the SH machine (fixed -- thanks to Him Who Shall Remain
 Nameless), a gmonitor display problem (fixed -- thanks to HWSRN), and
 a TUI offset bug (reported in detail by HWSRN).  None of those
 problems cost any observing time, need I say why?  All mechanical
 stuff worked very nicely tonight, thanks to Jon Davis especially, as
 well as Dave Woods and Mark Klaene for much hard work over the past
 week.
