I took an confirmation image of this transient object with 0.1m Refractors + SGIG STL-11000M CCD camera at Mayhill, NM, USA (T14, iTelescope.NET) remotely. Photometry was V=13.23. Position end figures of R.A. and Dec. were 47.97 and 31.19. My image is available at http://meineko.sakura.ne.jp/ccd/TCP_J16054809+2405338.jpg. Seiichiro Kiyota (Kamagaya, Japan)
