Abstract

The LSST project has acquired an all sky IR camera and started to investigate its effectiveness in cloud monitoring. The IR camera has a 180-degree field of view. The camera uses six filters in the 8-12 micron atmospheric window and has a built in black body reference and visible all sky camera for additional diagnostics. The camera is installed and in nightly use on Cerro Pachon in Chile, between the SOAR and Gemini South telescopes. This paper describes the measurements made to date in comparison to the SOAR visible All Sky Camera (SASCA) and other observed atmospheric throughput. The objective for these tests is to find an IR camera design to provide the survey scheduler with real-time measured conditions of clouds, including high cirrus to better optimize the observing strategy.
