The Photometric Period of V1112 Persei (Nova Per 2020)

摘要

A photometric study of V1112 Persei (Nova Persei 2020) has been undertaken at the urban Burleith Observatory in Washington, DC, where 2,400 CCD observations were obtained over a time span of 42.02 days. A photometric period was obtained: 2.2257 ± 0.0011 h, epoch (HJD) of minimum light 2459192.612, with amplitude 0.010 magnitude (Cousins I). The serendipitous discovery of two new variable stars, BD +43 984 and GSC 02891-02799, is reported.
