F. Watanabe (Nayoro Observatory, Nayoro, Japan) performed a follow-up observation for this transient using a 0.4-m f/10 Meili telescope (Meade Schmidt-Cassegrain telescope) + R-filtered CCD (SBIG STL-1001E) on Sep. 25.534 UT. The magnitude is measured to be R = 14.1 +/- 0.1 (reference stars from UCAC4 Rmag). The position end figures are given as 22s.63, 59".6.
