Lsst All-Sky Ir Camera Cloud Monitoring Test Results

The LSST project has updated the all-sky IR camera that was installed on Cerro Pachon in Chile to continue its investigations in cloud monitoring and quantifying photometric conditions. The objective is to provide the survey scheduler with real-time measured conditions of the sky/clouds, including high cirrus to better optimize the observing strategy. This paper describes the changes done to improve the detection performance of the first generation system and presents comparison results of visible and IR images.
