Scientific paper

The authors present optical flare photometry and a search for spotted variations on the star Gl 229. These results rule out the presence of a large-scale asymmetric spot distribution and indicate a low level of flare activity. This is in agreement with other indicators of stellar activity including coronal X-ray emission and radiative losses from the lower chromosphere as gauged from the strength of Ca H and K and the Balmer lines.
