Kcor is stopped until conditions improve. ___end___ GENERAL COMMENT BY mcotter: Sat Apr 17 23:47:56 GMT 2021 Cloud coverage is increasing. The dome shutter doors are now closed in the event of precipitation. ___end___ GENERAL COMMENT BY mcotter: Sun Apr 18 00:59:39 GMT 2021 I opened the dome shutter doors and tried to restart Kcor but clouds quickly came in from the west and began blocking the view of the Sun. In addition to the Orthographic clouds from the west, high altitude Cirrus clouds have increased and are now quite prevalent from zenith and across the western sky to the horizon. ___end___ GENERAL COMMENT BY mcotter: Sun Apr 18 01:58:45 GMT 2021 The morning was nice and clear but clouds moved into the viewing area in the early afternoon and conditions continued to degrade for the rest of the day. ___end___ ONSITE STAFF: mcotter
