A few minutes after 8 UTC, CO2Y tripped. 

We restarted all the models on OAF.  When I went to the chillers, only CO2Y had a low temperature warning, but there was no low temperature fault after clearing this and the chiller stayed powered on (normally after the warning is cleared the fault appears, when the fault is aknowledged the chiler shuts off.)  The laser also did not have a temperature fault when I went to turn it on, although it was off.
