We present the results from multi-wavelength monitoring observations of Narrow-Line Seyfert 1 galaxy Mrk 335 with AstroSat. analysed both X-ray (SXT and LAXPC) UV (UVIT) data source at two epochs, separated by $$\sim$$ 18 days. The was in a low flux state during observations, spectra were found to be harder than usual. presence soft excess identified broadband continuum modelled power-law black...
