We report the discovery of a bright (H = 12.77) brown dwarf designated SIMP J013656.5+093347. The discovery was made as part of a near-infrared proper-motion survey, SIMP (Sondage Infrarouge de Mouvement Propre), which uses proper motion and near-infrared/optical photometry to identify brown dwarf candidates. A low-resolution (λ/Δλ ~ 40) spectrum of this brown dwarf covering the 0.88-2.35 μm wavelength interval is presented. Analysis of the spectrum indicates a spectral type of T2.5 ± 0.5. A… 
A Brown Dwarf Census from the SIMP Survey
We have conducted a near-infrared (NIR) proper motion survey, the Sondage Infrarouge de Mouvement Propre, in order to discover field ultracool dwarfs (UCD) in the solar neighborhood. The survey was

TLDR
Three cool brown dwarfs are found that fall in the effective temperature gap between the latest L dwarfs currently known, with no methane absorption bands in the 1-2.5 µm range, and are proposed to be early T dwarfs, whose spectra are dominated by methane and water.
