TWP/SKYRAD/C3 - IRT damaged
DataStreams:twpskyrad20sC3.a0, twpskyrad60sC3.b1
Description:
The analog output of the IRT was damaged by a lightning strike. The problem was corrected 
by replacing the instrument with a spare. The damaged IRT was returned to the vendor for 
repair.

TWP/SKYRAD/C3 - Solar Tracker locking at solar noon
DataStreams:twpskyradC3.00, twpskyrad20sC3.a0, twpskyrad20sC3.a1, twpskyrad60sC3.b1
Description:
The Scitech solar tracker from SGP that was installed on 2005-12-01 after the previous 
tracker was damaged by lightning on 2005-11-14 has been hanging up every day at solar noon.  
In Feb, the sun moved from south to north and the Scitech tracker does not seem to be 
able to deal with this. During this period the operators power cycled the tracker between 
05:00Z and 10:00Z almost every day and data from around solar noon (03:30Z) until the 
power cycle are unusable for the measurements that use the tracker (NIP, B&W Diffuse, and 
shaded PIRs).
The problem was corrected when the Scitech tracker was replaced by a Brusag
tracker on 2006-03-10.
