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.
