Problems: 

# Screenshots are not working on observer1's console. This was first noticed at the end of observing last night. The problem persists today. The behavior is shown in the attached file. This looks like an x-server problem, typical of when an x-server is overloaded. Xserver may need to be restarted. Orphan process may be running.

#The DIMM1 FWHM data were missing from 3:40 to 7:00 (UT)

Comments: 

*Observing Plan*
# Full night DES observing
# 3 standards including: SDSSJ2140-0000, LDS749B_CCD_35, E8-A
# Obstac
# 3 morning standards including: SDSSJ0100-0000, GD71_CCD_35, SDSSJ0320-0000

*Conditions*
# Clouds: light cloud cover up most of the sky early in the night; 
# Bright moon: 76%
# Seeing: (Q1) 1.6", (Q2) 1.8", (Q3) 2.0", (Q4) 1.2"
# At beginning: high clouds covered most of the sky. ~10 deg C. Winds ~10 mph. Humidity ~20%
# At midpoint: high clouds covered most of the sky. ~12 deg C. Winds ~20 mph. Humidity ~20%
# At end: high clouds covered most of the sky. 13 deg C. Winds 12 mph. Humidity 13%

*Accomplishments*
# Observerd envening standard stars even though sky are covered with thin clouds
# Observed widefield ExpID: 574107 - 574253
# Observed SN-X1 ExpID:     574254 - 574259
