There is heavy snow at the White Sands Complex near Las Cruces, NM. About 6" of snow has fallen so far. Snow can cause the Ka-band science downlink to fade, and it completely faded at 1815 UTC (1:15 p.m. ET) and has not yet returned at 1915 UTC (2;15 p.m. ET). The S-band link is not affected by the snow and is still being received. When the snowfall abates we will again receive the science data.
Update 23-Jan-2015: Normal science data flow was restarted at 2204 UTC yesterday (5:04 p.m. ET). Many thanks to the people who cleaned the snow off the antennas!
