STATE of H1: Commissioning
SHIFT SUMMARY: So far today commissioners have taken the IFO up to 40W input power (with some low noise steps skipped).
LOG:

• 15:38 Lockloss - saturating suspensions and ADS excursions ~30s before.
• 15:45 Jim to site
• 18:2-19:15 Karen to MY 
• 20:15 Lockloss - arm power increasing before lockloss as had a few weeks ago (alog#58623), also ADC overflow, see attached plot.
• 21:12 Chandra to MY and VPW
• 22:03 Lockloss -  unsure why. From 40W input power!!!
  • During relocking, the ALS Y arm was in fault as fiber polarization was low, adjusted with Sitemap > ALS overview> Polarization correction box > followed instructions to change Chan2 PaddleX from -33.5 to -64.65 reducing ALSY polarization from 103% to 1%
