I read this this morning: PNV J20263897+4337182
It is located onyl 8' from V503 Cyg (UG). Might be visible on CCD frames of V503 Cyg...
The position coincides with the bright red object 2MASS J20263897+4337182 = WISE J202638.97+433718.2 (J = 9.78, J-Ks = 2.53), so probably not a nova.
Bright red object? Nothing is visible on DSS images... :O
Might be a faint mira?
Only one R and one I data in USNO B1.0: 17.87R, 14,65I (1972.)
No B data in USNO B1.0.
Seqplot doesn't shows any object at the given position. The faintest APASS object in the field is has 16.5V brightness (B-V=1,264) with 2 data, so I can assume the limit of the limit of this APASS field can be around 16.5V. (Unfortunately the PNV lies just outside of the V503 Cyg UNSO-Henden frames :(

This is not a nova, but previously unreported red variable (Mira or
semiregular). It shows large variability on Palomar red plates (R1=17.87 on
1953-06-14 plate, not visible on 1992-08-27 plate). Also, USNO-B1.0 gives
near-IR magnitude I=14.65 from the 1992-06-20 plate.
(...) It was already there 4 months ago on MASTER image:
