   One of the earliest L dwarfs within 10pc, indeed a query of SIMBAD
   for objects with plx>100mas (d<10pc) and L spectral types shows no
   objects with default types between the L0 companion to LP 388-55
   and 2MASS J00361617+1821104. This appears to be the most studied
   early L dwarf within 10pc, discovered by
