SGP/MMCR/C1 - TWTA Faulting
DataStreams:sgpmmcrmomC1.00, sgpmmcrmomC1.b1, sgpmmcrspecmomC1.a0
Description:
The MMCR transmitter (TWTA) has been having a low helix current fault.  This results in 
the transmitter shutting down.  However, the radar continues to collect data.  The MMCR 
restarts the TWTA at 0000 each day, hence the 2359 end times for many of these intervals.
