     1934  LA Mark5 pack NRAO-207 has a consistant red "o"       19666          
           for the seventh drive of the pack. Documentation                     
           indicated that this disk - drive 6 - of the pack                     
           may be slow but data should be ok.

0536-0733 *HN 1cm receiver temperature just shot way up.         19667  100  117
     0605 *HN 1cm cryo temp continues to rise, data is           19667          
           basically worthless. Removing HN from observing.                     
     0618 &HN tech Haenichen contacted, he doesn't think         19667          
           there is anything they can do for the 1cm tonight,                   
           will have to check it out in the morning. Also,                      
           weather conditions are against them, it just                         
           started sleeting which would make it dangerous to                    
           go climbing around on the antenna in the dark.                       
     0733  End.
