*Accomplishments*
#
# Calibration: Double set of dome flats 383749 to 383859 and 383860 to 383970
# Pointing Shot: 383973
# Defocus Shots: 383974, 75
# Wrong PropID for 383992 aborted
# 21:48 TOO QO95 200s z-band is 383993 engineering propid
# 21:52 TOO VS113 200s z-band is 383994 engineering propid
# 21:58 Start Obstac. Last before TOO is 384144. DES propid
# 01:59 VS113 is 384145 engineering propid
# 02:03 QO95 is 384146 then back on Obstac with DES propid
# Last Obstac is 384286, Last SS is 384301, Last Bias is 384312
# More than 300 WF images. Some z, mostly Y.
*Issues*
# 04:43 Broken Interlock. Component not ready is DECal. Alberto restarted the computer. Lost 7 minutes.
# No other.
