2 Light Curves for each night Marino, Giuseppe 2013-12-19 22:59 UTC The object was observed during 4 nights. Ensemble differential photometry was performed using 3 comparison stars. Rc-magnitudes for the comparison stars were derived from APASS by using the conversion formulae given by Munari, JAAVSO 40, 582 (2012).
