DQ Shift for Week of May 4th

Shifter: Pat Meyers

May 4th, 2015

  • Looks like maybe an EQ around 0100 UTC. One of these three? 1,2, 3?
  • Translational motion (but not vertical) at 300 level consistent throughout the day: 300 level page.
  • Sharp spike at around 1900 UTC in all sensors, not consistent with timing error/other channels that I can see.
  • 2000C mass position 1 is “high” and 3 is close to that —> 4V,-3.8V (see here)

  • EQ or something big between 1:30 and 3 am This one, I'd guess....
  • Sharp spike at 2000E station at 11:30UTC.
  • WTP showing non-stationarity late in the day in N/E channels.
  • 4850A mass position 1/2/3/timing quality all go crazy at 00:00UTC: seen here.
  • 2000C mass positions still high (see above link); 2000E mass position still nonsense.
  • 800 level mass position 2 high (and climbing throughout day today and yesterday) here.

  • Timing quality normal. 5 drops for underground stations spaced throughout day. Seems standard.
  • 300 station has spikes in it's time series: here
  • One especially large spike seen in all UG stations at ~22:30 UTC: seen here
  • 2000C E channel has a glitch at around 7:00UTC whose amplitude takes ~1 hour to decrease back to level of noise here.
  • ORO,WTP seeing some very interesting changes in amplitude throughout the day: ORO and WTP.
  • ORO, WTP and 2000C artifacts ONLY show up in N and E channels, not in Z channel.
