Kosmos status and re-try fixed it. Spec focus was same as last night 2940 (6C) We dropped an ARCTIC quad (actually all of them) while I was changing instruments tonight. The user was taking darks while I was changing, maybe a bad idea in retrospec. I tried moving it over the floor gently. I did an arctic init and that thankfully brought back the LL and UR quad. We ran in LL mode tonight. No other problems tonight. I took a test ARCTIC image in quad mode at the end of the night, All quads came back to normal levels except the UL which was still reading 0. Looks like ARCTIC will need a recovery done. This is the same behaviour that Amanda saw the other night as well when the quads dropped on her. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- BY02 ARCTIC I/H 01:10 01:40 Dropped quad (all) while mounting instrument.
