Subject:	SGP/TSI/C1 - Instrument failure
DataStreams:	sgptsiC1.00, sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1
Description:	The TSI-880 experienced a power and/or computer failure. It was replaced with a spare TSI-440 and data collection resumed 4/5/05. Note: this is a temporary replacement.

Subject:	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.
Measurements:	sgptsicldmaskC1.a1: PNG data stream - documentation not supported(png) sgptsiskycoverC1.b1: Percent opaque cloud(percent.opaque) Pixel count: number total thin(count.thin) Percentage thin cloud(percent.thin) Pixel count: number total opaque(count.opaque) sgptsiskyimageC1.a1: JPG data stream - documentation not supported(JPEG data stream - documentation not yet available)

Subject:	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.

Subject:	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.
