The Palomar Gattini-IR survey observed the location of the dwarf nova AT 2018jro (ASASSN 18abj; TNS 26163, ATEL #12295, and ATEL #12294) during regular commissioning operations. We report a J-band light curve for the transient derived from this data. The outburst was clearly detected on JD 2458461.92 at a J magnitude of 11.01, brightening by more than 2 mags from data taken 3 nights before. The photometry has been calibrated to nearby stars in the 2MASS catalog and is presented here (in Vega magnitudes).
