I set up a magnetometer at EY near the ESD chassis in the VEA for a blip glitch study (see upcoming log from Paul). The plot shows the channel names (12 and 13 are the Y and Z axes) and very high coherence between the mag and DARM at odd harmonics of 1 Hz. This is one of the new combs that Ansel identified and so this channel may also be useful in seeing if it goes away during the reboots on Tuesday.
