Date: 
Thursday, October 26, 2017
Telescope: 
CTIO Blanco 4-m
Submitter: 
Gourav Khullar
Submitter Email: 
gkhullar@uchicago.edu
Observer Support: 
Claudio Aguilera
Night Assistant: 
Hernan Tirado
Problems: 

Guider lost connection to the system at 00:50 UT, ceasing telescope operations. Operator/Support tried restarting the GUI twice, while keeping the SISPI connection intact; this did not work.Restarting the SISPI connection brought the guider back. SISPI, GUI connected properly to the telescope; observations resumed at 01:10 UT (we lost 15-20 minutes of observing time). Approximately half of Stripe 82 script was run; we resumed observations with obsTac (some of the Stripe 82 exposures still need to be done). Exposure 691112 might have been affected; Exposure 691113 was unsuccessful.
