           UT1-UTC correct, gps delta and vclock okay.                          
           (Except I couldn't check at PT.)                                     
           Main and backup communications with PT site down.

           Unstable power, possibly due storm in area. Going                    
           to wait a bit and repoint again.

0057-0228 *SC unclearable AZ#2 armature electronic circuit       19245  100   91
           breaker fault condition. Stowed antenna. Contaced                    
           oncall site tech, he will go out and replace                         
           fuse(s).                                                             
0318-0323 *SC autostowed. Power glitch. Repointed.               COM    100    5
     0320 %MK MASER is running on battery power.                 19246          
           Looks like the AC power supply for the MASER died.                   
           Data should be ok as long as the battery can power                   
          &the MASER. Contacted oncall site tech, he will head                  
           to the site.                                                         
0350-0436 %PT loss of communication. This was expected                          
           as a rental generator was going to be hooked up                      
           at the VLA.
