On Kissel's suggestion, flagging H1 data from 23:45-1:25UTC, due to snow plowing (by Bubba).  This is for CP2 access for LN2 delivery Tues morning.  Activity could be seen in our 3-10 & 10-30Hz bands.  This brought H1 range down below 50Mpc at times during this period.  Drifts were several feet high & it took him almost 2hrs just to plow just this short section.
