VACSTAT BSC3 glitch, looks like a false positive
VACSTAT reported a glitch in BSC3, H0:VAC-LX_Y8_PT132_MOD2_PRESS_TORR at 02:21:57 Sun 01 Sep 2024 PDT.
This looks like a sensor glitch, it is only 6 seconds wide and has no characteristic pump-down curve. Nothing was seen in the neighbourhood BSC2 at this time.
Attachment shows VACSTAT MEDM and ndscope of PT132 covering about 40 mins.
