ABSTRACT
We find periodic I-band variability in two ultracool dwarfs, TVLM 513-46546
and 2MASS J00361617+1821104, on either side of the M/L dwarf boundary.
Both of these targets are short-period radio transients, with the detected I-band
periods matching those found at radio wavelengths (P=1.96 hr for TVLM 513-
46546, and P=3 hr for 2MASS J00361617+1821104). We attribute the detected
