Fire alarm at the 4-m

 
The night of November 3 on Kitt Peak started with a commotion. The fire alarms sounded all over the mountain top and as I went outside to check, the lights were on in the 4-m building, lighting up the whole north end of the mountain. They had flashing red lights and a few vehicles driving around to determine what the problem was. Apparently it was a false alarm caused by a flakey smoke detector. This image shows the 4-m with bright lights, the building lit in red emergency flashing lights; below it is the Steward Observatory 90 inch telescope and on the left is the Spacewatch 0.9-m telescope. The exposure was 10 seconds at f/1.8, ISO 1600 with a 24mm lens attached to my Canon 20D.
