Problems: 

SISPI had problems in the afternoon, before calibrations (it didn´t restart). After consultation with CISS, the machine readout2 had to be rebooted. Everything ok after that. Thanks Petri. Calibrations started a little later than usual (~5:50pm)

DECAL problem at 9:20pm. Solved in the usual manner (rebooting the DECAL computer)

*Accomplishments*

# 2 standard star fields: E8-A, SDSSJ2140-0000

# Star flats in Y z i VR r g u (total time 2h40m; this time would be paid back on Tuesday night)

# DES Survey exposures mostly in Y 

# DES SN field C3 (filters z and i)

# 2015B-0322 Community script ran 4 times

# GPS check (OK)

# ToO script G184098-lmc-2.json (in directory ExposureScripts/2015B-0187/). Started at 5:57am

# Obstac again until sun altitude=-14

# 3 standard star fields: SDSSJ0200-0000, C26202/HST, SDSSJ084300-000000

 

*Narrative*

# Night clear (photometric). Since Star Flats were a priority, I started with those (under engineering Prop-ID 2013A-9999). Good seeing (~1 arcsec)

during these observations. Total tiem for sequences in all 7 filters: 2h 40m

# Seeing started to degrade and vary after the star flats, reaching up to ~2.2 arcsec at some point. Wind was moderately high during the second aprt of the night.

# Very smooth night
