                     APACHE POINT OBSERVATORY SDSS 2.5m
                              OBSERVING  LOG
The telescope was open most of the day.  It was open from 10 AM on.  The
encoders were checked for scale accuracy.  Right now the scale factor is
   Az -1.0270
   El -1.0279
   R   1.0256
Again we were blessed with great weather.  It was clear all night with
light winds.  The data was showing fwhm of 1.1 to 1.2 arcseconds for the
first part of the night and got a little worse toward the end.
We were on the sky and taking data starting at about 21:30.  After the moon
set and we found out where we were in declination, the telescope was moved
in elevation such that the gaps between the chips from last night's scan
were covered by tonight's.  The scan overlap finished at about 03:00.  Data
taking stopped at about 05:00 and the building was closed shortly
thereafter.  At this point it appears the data is in hand to create a
filled stripe of at least 2 hours in length of which an hour is in the
survey area.
