              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We opened not too long past sunset, once the traditional afternoon rains
had passed by.  Varying clouds caused occasional problems both first and
second half, but the observers were able to continue taking data through
the clouds, so I didn't count any of that time as lost.
The beginning of the night had a record or near-record for seeing with the
echelle: I got 0.48" on the final focus image.  It degraded somewhat after
that with most stars around 0.8-1 arcsec with the echelle, then a bit
worse when SPIcam was focused.  Later in the morning I did get 0.7" with
SPIcam, as well.
SPIcam had no problems with dark current tonight.  At one point we thought
the telescope pointing was off, but it turned out to be bad target
coordinates.  So there were no equipment difficulties tonight.
