  We report the discovery of two L dwarfs (the new spectral class defined for
dwarfs cooler than the M type) in a two-epoch CCD proper motion survey of 413
square degrees, complemented by infrared photometry from DENIS. One of them has
a strong lithium line and is therefore a brown dwarf. The other is a common
proper motion companion to the mid-M dwarf LHS 102 (GJ 1001), which has a well
determined trigonometric parallax. LHS 102B is thus the coolest L dwarf of
known distance and luminosity. Its infrared absolute photometry are very well
reproduced by the Allard et al DUSTY models.
