| 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. |

| 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. |
