Abstract
A photometric study of the fast galactic nova V1674 Herculis (Nova Her 2021, TCP J18573095+1653396) was undertaken at the Burleith Observatory in Washington, DC, and supplemented with photometry from the Crimean Laboratory of the Sternberg Astronomical Institute and the Astronomical Institute of the Slovak Academy of Science. A total of 979 CCD observations were obtained over a time span of 53.8 days, yielding an orbital period: 0.152934 d ± 0.000034 d, epoch (HJD) of minimum light 2459408.74789.
