Observing Specialist: Deglman
Opened at 18:55.  UW05 obtained bias and flat field frames with SPIcam.
The infrared flats were weaker on the left side, e.g.,
export/images/dalcanton/april6/apr6.0023.fits.  Scattered light problem?
The scope was pointing to the west for all flats.  Tried starting the DIMM
from the control room again.  SMALLSEARCH, BIGSEARCH, GOPOLARIS then
BIGSEARCH.  Went to DIMM dome to investigate.  FTP server was closed, but
apparently the DIMM software had found Polaris and started up correctly by
remote.  At 00:20 had wild image jumps of about 10 pixels and a few
directions /export/images/dalcanton/april6/apr6.0050.fits.  The guiding
data showed nothing suspicious.  The cloud camera stalled at about 02:30.
Morning flats were taken.  Closed at 06:30.
