Caption: Figure 4.
(Left) Lomb–Scargle power as a function of frequency of the light-curve solution, shown in inverse days, for observations from UT 2019 May 4 to 2025 July 20. The power peaks at a light-curve period of 0.0812 days, which is equivalent to a rotation period (which is twice the light-curve period) of 3.897 hr. (Right) Photometric data for 6993 phased to the rotation period of 3.897 hr and amplitude of 0.29 mag. Observations in the ZTF g (green), ZTF r (red), and ZTF i (purple) are corrected to the ZTF r filter in order to derive g − r and r − i colors of 0.57 ± 0.04 and 0.28 ± 0.03, respectively.
