Abstract: We report follow-up multifilter observations of the binary 2MASS J16211735+4412541 taken in BVRI colors in 2017 and 2018. We present the evolution of the shape of the light curve, as well as the preliminary results from modelling the system. Based on these and a spectrum showing double peaked Balmer emission lines, we infer that the system still contains an accretion disk and not a bare white dwarf.
