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 - Birds obstructing view
DataStreams:sgptsimovieC1.a1, sgptsicldmaskC1.a1, sgptsiskyimageC1.a1
Description:
Birds were frequently in the the field-of-view and soiling the mirror, affecting the 
visible sky image and resulting processed cloud fraction image. Bird deterant spikes were 
installed on top of the camera housing and arm on 5/16 which prevented their perching on the 
camera so that the impact on the sky image was reduced. But birds were still present 
around the edges of the mirror until additional spikes were installed on top of the four 
corners of the enclosure on 6/14.
