JeffB reports that instrument air pumps for the Corner station were both off, he talked to Kyle, he's going to manually run a pump until instrument air is above 50, to keep the pneumatic GVs open, preserving the lock, and buy some time for Kyle to make it to the site, Kyle is on his way.
GLITCH IN H1: glitch 2, I was watching DARM and this glitch appeared to happened at the same time that JeffB turns on the pump for Instrument air, at 15:28:29UTC.
GLITCH IN H1: possible glitch 1 - it's possible that there was also a glitch when JeffB cycled the pumps the first time at 15:19:42UTC.
CURRENT Pressure 76PSIG, JeffB running the pump manually
