  We present deep UV imaging observations of the Great Observatories Origins
Survey Northern (GOODS-N) field with AstroSat/UVIT (AstroSat UV Deep Field
north - AUDFn), using one far-UV (F154W, 34.0 kilosec) and two near-UV filters
(N242W, 19.2 kilosec; N245M, 15.5 kilosec). The nature of the UV sky background
was explored across the UVIT field and a global mean and rms was estimated for
each filter. We reach 3$\sigma$ detection limits of $m_{\rm AB}$ $\sim$ 27.35
mag, 27.28 mag and 27.02 mag for a point source in the F154W, N242W and N245M
bands respectively. The 50\% completeness limits of the FUV and NUV images are
$m_{\rm AB}=$ 26.40 mag and 27.05 mag respectively. We constructed PSFs for
each band and estimated their FWHM, which were found to be almost the same:
1.18" in F154W, 1.11" in N242W, and 1.24" in N245M. We used SExtractor to
separately identify sources in the FUV and NUV filters and produce the UV
source catalog of the entire AUDFn field. The source count slope estimated in
FUV and NUV is 0.57 dex mag$^{-1}$ (between 19 - 25 mag) and 0.44 dex
mag$^{-1}$ (between 18 - 25 mag), respectively. The catalog contains 6839 and
16171 sources (brighter than the 50\% completeness limit) in the FUV and NUV,
respectively. Our FUV and NUV flux measurements of the identified sources
complement existing multi-band data in the GOODS-N field, and enable us to
probe rest-frame FUV properties of galaxies at redshift $z < 1$ and search for
candidate Lyman continuum leakers at redshift $z > 0.97$.
