Identification of WISE J000100.45+065259.6 as an M8.5+T5 Spectral Binary Candidate

[not part of RNAAS note] We report the discovery of WISE J000100.45+065259.6 as a very low mass star/brown dwarf spectral binary candidate, on the basis of low resolution near-infrared spectroscopy obtained with IRTF/SpeX. Decomposition of the spectrum indicates component types of M8.5+T5 with a predicted $Delta{J}$ = 3.5. As the majority of confirmed spectral binary candidates to date are very closely-separated systems ($rho$ $lesssim$ 3 AU; $P$ $lesssim$ 15~yr), this source may provide mass measurements across the hydrogen burning limit within the decade.
