Abstract
We report RcIc light curves of 2 novae in the M 31 galaxy which were detected in the four year Nainital Microlensing Survey. One of these novae has been tracked from the initial increase in flux while other has been observed during its descending phase of brightness. The photometry of the first nova during the outburst phase suggests its peak Rcmagnitude to be about 17.2 mag with a flux decline rate of 0.11 mag day -1 which indicates that it was a fast nova. A month after its outburst, it shows reddening followed by a plateau in Ic flux. The second nova exhibits a bump in Rcand Ic, possibly about three weeks after the outburst.
