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

Clear skies,

Seems holding steady

I don't know about rebrightening, but for my eye V392 Per has been holding rather steady for the past 6 nights.  Tonight I estimated 8.6 mag.

Plummeting

Wasn't able to view yesterday, but seemed to plummet since two days ago, from 8.6 to 9.3.  Maybe I did witness a rebrightening then.
