Abstract:
We report R ̜ I ̜ 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 R ̜ magnitude 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 I ̜ flux. The second nova exhibits a bump in R ̜ and I ̜ , possibly about three weeks
after the outburst.
