The DSC has returned to APO. It now holds only 15 hours worth of liquid nitrogen in its dewar. Our fill schedule for this dewar will be once every 12 hours (temperture cycling the dewar causes serious chip contamination, which we want to avoid at all costs). This means that the dewar will need to be filled once during the night, generally between 03:00 and 05:00 Mountain Time, depending on what time it was filled during the previous afternoon. We'll try to make the impact of this operation as small as possible on the observers. We will, at least, need to be up in the enclosure with a flashlight for these dewar fills. -Karen G.
