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."

Confirmation, spectroscopy, multiband photometry, and precise astrometry are very urgently required.

Clear skies,

V392 Per very long outburst in 2016 February–April

The ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) recorded a dwarf nova outburst with a very slow (GK Per-like) rise in 2016 February/March (that outburst was visually detected by Carey Chiselbrook at mv= 14.2 on 2016 Feb. 28.04722 UT). The very slow rise to outburst maximum indicates a long orbital period. Final AAVSO observation before solar conjunction: 2016 Apr. 19.86573 UT, V= 14.341 mag (Steve Johnston).
