TWP/SKYRAD/C2 - Tracker Problem

The observers reported that the tracker was not shading the radiometers.
The sun sensor was damaged by moisture due to a missing front window.  The tracker had 
been in sun-sensing mode so required the sensor to maintain its proper orientation.  Troy 
Culgan placed the tracker in time-track mode (calculates solar position based on time, 
date, and location) until the sun sensor can be repaired.

TWP/SKYRAD/C2 - UVB Data questionable/incorrect due to uncontrolled sensor temperature

The UVB was not temperature controlled to 25C as required
to ensure accurate data.  UVB data should ONLY be used after 
checking both the bit_data and twpskyrad20sC1.a1 uvb_temp
or inst_down_uvb_temp.  UVB data where the UVB temperature
was outside the range of 24-26C should not be used.
