Subject:
TWP/SKYRAD/C3 - tracker inoperative
DataStreams:twpskyrad60sC3.b1, twpskyrad20sC3.a0, twpskyradC3.00
Description:
A lightning strike at Darwin removed the tracker from service.  Instruments installed on 
the tracker were rendered either inoperative or were not shaded during this time period.  
The longwave hemispheric instruments PIR1 and PIR2 appear to have been unaffected.  They 
are not suseptable to incorrect tracker operation.  The downwelling hemispheric shortwave 
PSP instrument mounted on Skyrad will not be affected by incorrect tracker operation.
