Date: 
Sunday, February 24, 2019
Telescope: 
CTIO Blanco 4-m
Submitter: 
Lara Cullinane (1st half), Sidney Mau (2nd half)

Observer Support: 
Manuel Hernandez
Night Assistant: 
Alberto Alvarez
Also Present: 
Clara Martinez-Vazquez, Douglas Lee Tucker
Problems: 

None.

Comments: 

[Observers]: Lost about 15 minutes due to issues with the remote observing interface from Fermilab; these are known issues and were resolved accordingly.

[Clara Martínez-Vázquez]: Actually, lost about ~6 minutes. Here is the explanation: 

It seems that the problem was due to SISPI not deleting exposures if the mouse is over them. The observers run out of exposures in the queue and for this reason there was lost time until we managed to understand the situation. 

This happened between the exposures 827397 and 827398:
 
expnum     ra    dec    utc fil  time  
827397 160.21 -18.05  05:35   i    90 
827398 136.20  -8.03  05:44   i    90 
 
Taking into account the exposure time and the movement of the telescope, the lost time was ~6 minutes.
