UPDATE: H1 Back To OBSERVING

As mentioned earlier, Tony (w/ Keita & Sheila on TeamSpeak) had H1 well on its way to NLN (after the big Phillipines EQ + Hardware Watchdog Recovery + the other "ongoing" issues all happening at the same time!).

Now that H1 is at NLN, it's been decided to keep H1 in OBSERVING at this lower BNS range (due to 20-50Hz noise seen on DARM, tagging DetChar) to get some single-detector-OBSERVING in ....BUT Fri night, Robert was allowed COMMISSIONING time if he wants it (H1 range is lower (~140Mpc), so H1 may possibly be too low for his work).

The other change is the Vertical Offset changes from yesterday have been reverted for ITMx, ITMy, & BS (see attached for SDF diffs which were ACCEPTED for this).  H1 also had Gaurdians for automated operation from me last night; IFO NOTIFY and H1Manager are now set to IDLE.

Finally, a new NOTE:  IMC_WFS has a notification:  "IMC WFS not centered" now flashing every few seconds.  I hadn't seen that yesterday.
