Yuji Nakamura, Kameyama, Mie, Japan, reports his discovery of this TCP (mag 6.2) in Per on a CCD frame taken on 2018 Apr 29.4740 UT (limiting mag 12.5) using a 135mm f4.0 lens. The object was not shown on a frame taken on 2018 Apr 21.4627 UT (limiting mag 12.5). There is a UG type variable star V392 Per at this position.

Photometry results were B=7.65, V=6.73 and Ic=5.23 with 0.25-m f/3.4 astrograph + SBIG ST-10XME CCD (T5, iTelescope.NET at Mayhill, USA). Comparison star was TYC 3347-712-1 (V=7.23, B-V=1.111 and V-Ic=1.07). Position end figures were 21.36 and 26.18 in R.A. and Dec. Seiichiro Kiyota (Kamagaya, Japan)

Hiroyuki Naito, Nayoro Observatory, and Tatsuharu Ono, Hokkaido University, report that a low-dispersion spectrum (R about 300 at 650 nm) of this object was obtained on Apr. 29.58 UT using the 1.6-m Pirka telescope (+ NaCS) at the Nayoro Observatory. The spectrum shows some unidentified absorption lines on a very red continuum, which may indicate high reddening.
