Earlier in 2021, Vlad performed six time-series photometric observations on LCO and BARO observatories of a nova like variable star that is also an eclipsing binary. Under the guidance of Dr. A. W. Shafter of San Diego State University, he reduced this data and TESS data and combined it with 52 historic eclipse observations to update the eclipse ephemeris. The results suggest the orbital period is decreasing from extrapolation of the best-quadratic fit of the O-C plot. Full AAS Research Note here.
