JHK_s data for ρ Oph YSO 2MASS J16272658−2425543, folded to a period of 2.9603 days. The identification of this period is uncertain. The object exhibits variability on a 3 day timescale, but the observed variability is not entirely consistent with this period derived from our analysis. Possible solutions include spotting and semiperiodic veiling from circumstellar material.
