Date: 
Tuesday, October 31, 2017
Telescope: 
CTIO Blanco 4-m
Submitter: 
Gourav Khullar
Submitter Email: 
gkhullar@uchicago.edu
Observer Support: 
Claudio Aguilera
Night Assistant: 
Manuel Hernandez
Problems: 

Issues with TCS. Took 10-15 minutes to re-establish connection with the telescope. Pointing targets observed again. All normal. Lost time was compensated by the lack of a 3rd optimal standard star in the sky (the plan was to only observe two established standards in the evening).
