Abstract:
We present a summary of Kepler and supporting observations of a nearby L1 dwarf. We find periodic 8.9 hour variations with an amplitude of 1.5. The surface features have remained consistent for 15 months. Magnetic starspots are a plausible explanation, but a cloud-related feature is also possible. We also detect white light flares as powerful as the strongest solar flares, despite the low temperature of the photosphere.
