After speaking with Keita we agreed to switch the phase camera back on to try and get some more data before pulling it out tomorrow. It was switched back on at 1:50 PST (1256939418). I have placed a plate between the camera and POPX which on Saturday appeared to fix the scattering shelves we were seeing when the camera forces its internal fan on to cool down, this was happening before every ~2700.  Apart from that, Robert and I could not see any direct coupling into DARM when it was on last week. Although we were concerned about the power supply fans being on so close to ISCT1, hence why it was switched off on Friday.

If the fan does comes on it is quite visible in the POPX DC channels when the plate wasn't in, plot attached: H1:ASC-POP_X_DC_PIT_OUT16, H1:ASC-POP_Y_DC_PIT_OUT16
