  Extensive multi-wavelength studies of novae have been carried out in our
galaxy and in M31 for decades. However, UV studies of extragalactic novae are
limited, especially those in quiescence. For the first time, we present a UV
catalog of novae in M31 using the archival AstroSat UVIT imaging data. We used
two image subtraction techniques to retrieve objects located deep into the M31
central region. We have found 42 novae in total in the UVIT images, 15 of which
have been detected in multiple filters in FUV and NUV. The novae detected at
quiescence show signatures of accretion disk from their UV spectral energy
distributions, whereas those in the outburst phase show signatures of
pseudo-photosphere. A few novae were also detected in multiple epochs. Some
show a near-constant FUV magnitude at quiescence, while others caught near the
outburst reveal pre-eruption dips in their light curves. We conclude with a
discussion on the significance of UV surveys in illuminating theoretical
predictions for novae systems, including detecting the elusive early UV flash.
