Per cryo group (Robert Norton)'s request, I reduced the Hall A load to bare minimum: fan speed to 24 Hz for both loops, HP heater to 0 watts for both loops. Target temperatures fluctuate a little bit, but stays close to the desired value (19-20K LH2, 23-24K LD2). The ESR flow reduced to 9.4 g/s. Will continue to monitoring while Hall C cooldown is going on.
