# Photometric study of two Novae in M31

Abstract : We report $R_cI_c$ light curves of 2 novae in M31 galaxy which were detected in the four year long 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 first nova during the outburst phase suggests its peak $R_c$ magnitude to be about 17.2 mag with flux decline rate of 0.11 mag day$^{-1}$ which indicates that it was a fast nova. After a month from its outburst, it shows reddening followed by a plateau in $I_c$ flux. The second nova exhibits a bump in $R_c$ and $I_c$, possibly about three weeks after the outburst.
