From 2:00 target density falls below 2E10 and started decreasing to the E9 range. At 2:40 we started playing with x-y to get to higher density. At 3:30 we are at 5/6E10 and waiting to see if it stabilizesto that or if it needs more playing.

Target density has not improved despite efforts last night. Mid 10 - low 11 density range. We have asked HKR to remove beam from the ring and allow access so Nikos can change the nozzle.
Beam off now, access granted. Will begin warming nozzle. Internal cave work on changing nozzle expected to start at 11
Run stopped.
