Abstract
The Telescope Array (TA) is the world-largest cosmic ray detectors in the northern hemisphere, with fluorescence detectors (FDs) and a surface detector (SD) array. We have developed a cloud monitoring system for the TA sky to monitor weather condition during FD observation periods. We use a CCD camera with a fisheye lens to evaluate cloud coverages by identifying stars in the TA sky and comparing with a star catalogue. We will report the hardware of the monitoring system and details of the data analysis.
