Abstract : The primary aim of our project is to produce a catalogue of bright sources in Far ultra-violet and Near ultra-violet band as well as study their variability on short timescales. The excellent spatial resolution of UVIT and its unique feature of simultaneous imaging in both FUV and NUV band enables us to produce UV colour for our detected sources, as well as simultaneous variability studies in both the bands help us to study the nature of UV emission from these sources. We have analysed the deep UVIT field obtained for observation of Seyfert galaxy IC4329a and detected 1000 sources in FUV and 3133 sources in NUV band above 3 sigma SNR level. We performed astrometry and photometry on all the detected sources and produced a catalogue containing their position, Far and near UV flux, magnitudes and UV colours. We are also investigating the UV variability for some bright sources in our field on short time scale for the first time.
