           VCLOCK, GPS Delta, and UT1-UTC check ok.                             
     0308  Begin.                                                               
          *SC Weather station is not working. Temp. and dew                     
           point reading are not correct.                                       
     0308 %HN Maser Right and Left ion pump currents are way     13027          
           out of range.                                                        
0308-0909 *NL Antenna is not useable. Major problem with the     13025  100  361
           EL axis. Site tech was not able to repair.                           
     0308 *HN WEA: Snowing, snow in the antenna.                                
0325-0330 *HN El currents are excessive due to snow load.        WEA    100    5
           I am dumping the snow.                                               
           Seems to have helped. Currents are near normal.

     0708 %FD Bad readbacks on drive 1, tracks 4,8,12,14,16                     
           20, and 22. All others ok.
