F. Watanabe (Nayoro Observatory, Nayoro, Japan) performed a follow-up observation for this transient using a 0.4-m f/10 Meili telescope (Meade LX200-40ACF) + R-filtered CCD (SBIG STL-1001E) on Apr. 13.453 UT. The magnitude is measured to be R = 14.1 +/- 0.1 (reference stars from UCAC4 Rmag) and the position end figures are given as 37s.87, 52”.2.
