The main activity occupying IceCube’s winterovers last week was running DOM calibration on all of IceCube’s in-ice modules, a big effort compared to their usual task of calibrating just the IceTop DOMs. Besides other work on the detector, they also had emergency response training and put in some time helping deep clean the galley chairs (sounds fun). As the darkness has increased over the past weeks, visibility issues with the flag line out to the IceCube Lab were becoming apparent, and we know how important those flag lines are to the winterovers. So Marc installed reflective tape on all the flags, making the whole line more easily visible under the light of headlamps.
