We present a simultaneous, multi-wavelength campaign targeting the nearby(7.2 pc) L8/L9 (optical/near-infrared) dwarf WISEP J060738.65+242953.4 in themid-infrared, radio, and optical. Spitzer Space Telescope observations show novariability at the 0.2% level over 10 hours each in the 3.6 and 4.5 micronbands. Kepler K2 monitoring over 36 days in Campaign 0 rules out stableperiodic signals in the optical with amplitudes great than 1.5% and periodsbetween 1.5 hours and 2 days. Non-simultaneous Gemini optical spectroscopydetects lithium, constraining this L dwarf to be less than ~2 Gyr old, but noBalmer emission is observed. The low measured projected rotation velocity (vsin i < 6 km/s) and lack of variability are very unusual compared to otherbrown dwarfs, and we argue that this substellar object is likely viewedpole-on. We detect quiescent (non-bursting) radio emission with the VLA.Amongst radio detected L and T dwarfs, it has the lowest observed L_nu and thelowest v sin i. We discuss the implications of a pole-on detection for variousproposed radio emission scenarios.
