Abstract
We report on a search for flaring and BY Draconis type variability on the M-dwarf Balmer emission line star, Gliese 867 B. The time-averaged flare energy in the Johnson U-band is similar to that measured in 1977 and 1978. A typical wave4ike variation of 0.15 magnitudes, seemingly due to rotational modulation of large spotted areas, was observed in the V-band with a period 1.95 days.
