TWP/SKYRAD/C3 - Tracker inoperative

The tracker at Darwin failed 01/23.  The tracker was power cycled on 01/27 and it returned 
to normal operation.

The affected data streams are short_direct_normal (NIP) and down_short_diffuse_hemisp 
(8-48).  

The down_short_hemisp are not affected.  

The down_long_hemisp1 and 2 (PIR1 and PIR2) should not be affected but direct sun can 
affect individual instrument performance.
