This Astronomical monitor is an all sky CCD camera that determines the extinction coefficients in the Johnson B, V and R photometric bands. AstMon-UCM also maps the night sky brightness of the visible sky. The collected data are useful to establish the quality of the sky and the evolution of its brightness due to the effects of the Light Pollution in Madrid.
