SGP/TSI/C1 - Birds obstructing view
DataStreams:sgptsicldmaskC1.a1, sgptsimovieC1.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.

SGP/TSI/C1 - Contamination of mirror
DataStreams:sgptsicldmaskC1.a1, sgptsimovieC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.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.
