- Status: Jason and Ryan S (with support from Jenne) installed a new NPRO as planned and then watched to see if there were any glitches. If there were, they would know that it wasn't the NPRO as the culprit. Seeing as there were not, they made the decision to swap out the old NPRO entirely. This will take H1 down for 3-4 days as they bring the PSL back up (time for course alignment, mode matching, etc.). This is still ongoing.
