Abstract : Low mass YSOs undergo episodic luminosity outbursts are classified as FU Ori or EX Ori based upon the strength and duration of outbursts. These episodic outbursts accompanied by sudden enhancement of inflow of gas from accretion disc to star. Outbursts mechanism are poorly understood though several mechanisms have been proposed. Here we present the results from our continuous spectroscopic and photometric monitoring campaign starting from 2015 to 2019 using 1.3m ARIES DOT and 2m HCT in optical and NIR wavelengths, of the source V960 Mon which had an outburst in year 2014. We will discuss the post outburst light-curve, colour evolution, spectral line evolution etc., of V960 Mon during this period.
