We present our analysis of Kepler K2 data of EPIC 212707862, a pulsating subdwarf B star (sdBV). We extracted 12 significant pulsation modes from nearly 79 days of continuous data gathered during Campaign 6. In the case of this star we did not find any signs of multiplets which would enable us to derive a rotation period. We also searched for period-spacing sequences to perform a mode identification, and we successfully identified modal degrees of 11 of 12 detected modes.
