F. Watanabe (Nayoro Observatory, Nayoro, Japan) performed a follow-up observation for this transient at the predicted position of 2MASS J04195212+4233304 using a 0.4-m f/10 Meili telescope (Meade Schmidt-Cassegrain telescope) + R-filtered CCD (SBIG STL-1001E) on Nov. 23.396 UT. The magnitude is measured to be R = 18.1 +/- 0.1 (reference stars from UCAC4 Rmag).
