Abstract

We report on an analysis of flaring and BY-Draconis type variability on the Balmer emission line star, Gliese 867B. The time-averaged flare energy in the Johnson 1-band is similar to that measured in 1977 and 1978. A variation of 0.15 magnitudes was observed in the V-band with a period l.95 days.
