          *Overcast conditions at NL, OV and BR. Also fog at                    
           BR and snow in the dish.

2157-0658 *HN has several warm receivers due to the loss of      13181   50  270
           a cryo compressor earlier today. The 6cm, 2cm and                    
           1cm receiver are all warm, but they are cooling now.                 
2157-0658 *HN 7mm receiver is also warm, though this problem     CRYO    17   91
           is unrelated to the cryo compressor problem that                     
           affected the other receivers.

           one of the motors. Cleared error and restarted scan                  
           to load proper position command.
