Huehnerhoff Big storm system moving in at start of night. High winds and impending threat of precip prevented opening. Around 2300MT the clouds cleared but the humidity stayed high for the remainder of the night. The regular DIS mask wheel is now back in DIS. The mask file has also been updated. As usual with these cold temperatures the slitviewer shutter was sticking pretty badly. Every other image was not usable.
