Announcement appearing only an hour, or so, ago on the AAVSO's Forum:

 

"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.

 

This position of this reported (but as yet unconfirmed) nova also corresponds to the known UG-type dwarf nova V392 Per, usual magnitude range 14.1-16.9 . If indeed a nova and identical with V392 Per, this would probably be an event unique in the annals of variable star astronomy, as I cannot recall its like.

I'm locking this version. Normally we don't allow duplicate posts but given the need for urgent data, I'll allow this one. Interested parties can comment in the Obs Astro-Phy forum - the thread is here.
