SGP/TSI/C1 - Heater problem
DataStreams:sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1
Description:
The TSI was converted from a model 880 to 660 which requires separate power for the mirror 
heater. The heater was not powered during this period so morning dew and other 
condensation was not quickly evaporated.

SGP/TSI/C1 - Contamination of mirror
DataStreams:sgptsiskycoverC1.b1, sgptsiskyimageC1.a1, sgptsicldmaskC1.a1, sgptsimovieC1.a1
Description:
A persistent bird was landing on and polluting the mirror, multiple times throughout the 
day. Spikes were placed on the corners and top of the instrument (an affective deterrent 
in the past) but this bird had the agility to perch on the top-center of the mirror.

SGP/TSI/C1 - Water on lens
DataStreams:sgptsiskycoverC1.b1
Description:
After a rain episode, drops of water collected on the lens window causing the cloud 
fraction values to be suspect.

To prevent this, a drip edge was formed around the bottom of the enclosure with thick 
electrical or splicing tape.
