  We discover a late-type L dwarf, WISEP J060738.65+242953.4 (W0607+2429), by
comparing the Wide-field Infrared Survey Explorer (WISE) preliminary data
release to the Two Micron All Sky Survey (2MASS) in search of high proper
motion objects (>0.3" yr^-1). W0607+2429 was found to have a proper motion of
0.57 +/- 0.02" yr^-1. Based on colors and color-color diagrams using 2MASS and
Sloan Digital Sky Survey (SDSS) photometry, we estimate the spectral type
(optical) to be L8 within a spectral sub-type. Based on the spectral type
estimated we find W0607+2429 to have a distance of 7.8^(+1.4)_(-1.2) pc, making
it one of only four very-late L dwarfs within 10 pc, and the third closest L
dwarf overall. This close L/T transition dwarf will play a pivotal role in
resolving outstanding issues of condensate clouds of low temperature
atmospheres.
