Also Present: 
Linda French, Robert Stephens, Kyle Connour, Javier Rojas
Problems: 

At 00:10, there were several (a couple ?) SISPI alarms reporting that the was a compressed air pressure problem, and the filter-GUI on the ICS was showing a variable (and descending) Supply Pressure value. Javier Rojas, Claudio A., and Rodrigo H., investigated the problem, concluding that in fact, it looks like a faulty sensor (cRIO ?) reading in software is falsely showing that the pressure is dropping. 

No observing time was lost -- great detective skills by Javier, Rodi, and Claudio !
