Photometry of Gliese 372 was obtained during the 1996-1997 and 1997-1998 observing seasons. Our 3σ limit on the presence of night-to-night variations, such as those due to eclipses or starspots, is ±0.024 mag. Over a single night, our limit on the presence of flares, eclipses, or other photometric variations is typically ±0.02. If the system is eclipsing, there was a 40% chance that we would have detected the eclipse based on the quoted uncertainties of the ephemeris. The observed lack of flares or photometric variations due to starspots suggests a low level of stellar activity.
