A. Phase-folded light curve of 2M J0746+20A from all three epochs, after subtracting out the secondary period of 2.14 hours. These unbinned data points are folded to a period of ∼3.32 hours. The observed sinusoidal variability to the same reported period from Harding et al. (2013b), shows that this dwarf is stable on timescales of years. B. The same data in plot A except binned in phase by a factor of 20 for clarity.
