The current fading began in early May 2022 according to ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) data (complete): https://asas-sn.osu.edu/sky-patrol/coordinate/2c766f33-797f-437f-9109-bff0ee...
AAVSO data: https://app.aavso.org/webobs/results/?star=V482+Cyg
Photometric (e.g. V band) and spectroscopic observations are encouraged. The Vmag range in VSX is 10.65 - <14.5.

There is a suggestion that the RCB star V482 Cyg may be fading. The star has been pretty much inactive since June 1996 when it faded to magnitude 13.0 and recovered to maximum brightness 12 months later (a deeper fade to magnitude 15.0 occured in 1990). Since then there have been small amplitude variations of 0.5 mag either side of magnitude 11.0. Latest magnitude in the AAVSO database is 11.9mv.
Charts are available from both BAAVSS and AAVSO.
Further observations are requested.
