  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 the
mid-infrared, radio, and optical. Spitzer Space Telescope observations show no
variability at the 0.2% level over 10 hours each in the 3.6 and 4.5 micron
bands. Kepler K2 monitoring over 36 days in Campaign 0 rules out stable
periodic signals in the optical with amplitudes great than 1.5% and periods
between 1.5 hours and 2 days. Non-simultaneous Gemini optical spectroscopy
detects lithium, constraining this L dwarf to be less than ~2 Gyr old, but no
Balmer emission is observed. The low measured projected rotation velocity (v
sin i < 6 km/s) and lack of variability are very unusual compared to other
brown dwarfs, and we argue that this substellar object is likely viewed
pole-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 the
lowest v sin i. We discuss the implications of a pole-on detection for various
proposed radio emission scenarios.
