Abstract
We present high-quality BVRI CCD photometry of the variable star V716 Monoc erotis (= NSV 03775). We confirm it to be an RR Lyrae star of variability t ype ab (i.e., a fundamental-mode pulsator) and determine its metallicity ([ Fe/H] = -1.33 +/- 0.25), luminosity (M-v = 0.08 +/- 0.06), and foreground r eddening [E(B-V) = 0.05-0.17] from the Fourier components of its light curv e. These parameters indicate a distance of 4.1 +/- 0.3 kpc, placing V716 Mo n near the plane of the Galaxy well outside the solar circle.
