State of H1: IFO is locked at DC_READOUT. Environmental conditions are not that favorable. Winds are a Fresh Breeze with gusts to Near Gale (19-24 base, gusts to mid-30s). Seismic activity is elevated but still below 0.5um/s, microseism is also elevated and getting worse due to a mag 6.3 EQ in the Philippines. Set ISI-Config set to EARTH_QUAKE_V2.            
Commissioning: The commissioning team is working feverishly ahead of projected arrival of the EQ.

Shift Detail Summary: It was a struggle to relock the IFO after the Philippines earthquake. With much assistance and perseverance, were able to relock and eventually take the IFO to NOMINAL_LOW_NOISE. The environmental conditions are good. Wind is no more than a Light Breeze (max 7mph), Microseism is centered around 0.08um/s. However, seismic started to ring up due to a Mag5.2 EQ near New Zealand, which eventually broke lock. Was able to switch the ISI to Eaeth_Quake_V3 before Lockloss, but not soon enough to prevent the Lockloss. 
  
The New Zealand EQ was followed by back to back Mag4.9 & Mag4.7 earthquakes near the Reykjanes Ridge. Seismic recovered in about an hour. Much trouble relocking, and Roll Modes still a bit elevated. Finally, able to get to NOMINAL_LOW_NOISE with Intent Bit set to Observing. Will take a small success and call it a night before another earthquake comes along to break the lock.
