TWP/SKYRAD/C1 - Tracker Failure

The solar tracker at C1 failed to wake up the morning of 6/10 approximately 2000GMT. Ops 
discovered problem and reset tracker 6/12 approximately 0800GMT.

Tracker dependent instrument data is inaccurate - this includes the short_direct (NIP) and 
down_short_diffuse_hemisp (8-48). The down_short_hemisp (PSP) and down_long_hemisp (PIR) 
are unaffected.
