"2018 04 29.4740 UT
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,

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).

Pavol A. Dubovsky (Slovakia) writes in vsnet-outburst 22120: "I can confirm the presence of the bright object at the position of V392 Per. I started multicolor photometry."
I'm working on an AAVSO Alert Notice for this nova eruption. If you have not already submitted your observations to the AAVSO International Database, please do so as soon as possible. I will be issuing the Alert Notice later today and would like to include your observations in it.
Many thanks, and Good observing,

AAVSO Alert Notice 633 announces and reports on the nova outburst of the formerly UG-type dwarf nova V392 Per. Please see the notice for details and observing instructions, especially regarding a close-by companion.
Many thanks, and Good observing,
