CP4 is baking at a rate of around 0.7C/hr. Flow is still 80% restricted at return duct. Kyle, Gerardo and I are splitting shifts to monitor pressure and temperatures remotely. Next week we'll start the regen GN2 heater. 

Temps are monitored here: https://lhocds.ligo-wa.caltech.edu/cr_screens/png/video0-1.png, and also at CP3's discharge TE202A channel (we are unofficially calling it GV11 air temp).

The heater is controlled by the reading of thermocouple installed at supply exit, which is the warmed spot, as expected.
