Ops EVE MidShift Report

We have been Locked for 19hrs 20mins. At 00:00UTC, we did get a notification on Verbals that WAP was on in the LVEA, EX, and EY, which it wasn't, but it's been quiet besides that.

However I did notice that the temperature of Rack 2 in the Y EBay has been rising in temperature over the past day, starting possibly around 8/11 23:19UTC (attachment1), and the current temp reads as almost double the nominal temp. Attachment2 gives a zoomed out timeline, showing that besides the power glitch that resulted in a partial power outage from August 5th (72000) and a period of time 17 days ago(unsure of the cause of that), the rack temperature has not gotten this high in multiple months. Tagging PEM and SYS (not sure if SYS should be tagged).
