Visual check

15:00: we climbed on telescope and had a visual check of the LGSWs and LAS boxes status.
  • The 2 LGSWs appear very muddy, a lot of mud water accumulated on both the flange of the entrance windows and of the Pockels cells (inside the WFS). Also entrance windows show a lot of mud water footprints, moreover the input lens of the patrol cameras are very dirty too.
  • DX-PCD has quite a lot of dust/mud accumulation on the side facing the Pockels cell flange, the SX-PCD seems cleaner (just regular dust accumulation?).
  • DX-PNCCD must be pumped, pressure is about 33mbar. The Sx-PNCCD gauge had low batteries and we could not measure properly. We did not check the connectors on the PNCCDs back side.
  • Both electronic racks seem dry and clean inside even if the DX one had some water accumulated on the plastic tarp covering it...
