Aurora = Very Quiet - Faint arcs visible at times, far to the north
Cloud = Variable, but generally poor
Magnetometer = Very quiet
ASC = Unknown
Digital_ASC = Ran all night, good data
MSP = Ran all night on all channels
SDI = Ran all night, fair data
Comments = Lots of moonlight. The MSP and ASC also show plenty of cloud, but I don't think it was very thick. MSP and ASC had snow on their dome & slit respectively, especially early in the night. But the SDI dome sheds its snow much quicker than other instruments. All up, the SDI data are less than ideal.
