Using the AAVSO finder chart and Stellarium made it quite easy to find and estimate the magnitude. Will be interesting to see how my guess compares to more experienced nova observers.

Jeff, that estimate is very good and aligns with other estimates, including mine. You obviously have a talent for this
. Magnitude estimates can be found here

It now appears to be in the 5.5-5.7 range.
The comparison sequence has been extended up to 4.5 so you could update your charts. They recommend plotting at AB scale (7.5 degrees) but if you go out to A scale (15 degrees) you get a handy 5.7 comparison star. You can get these by asking for charts X40364JR or X40364ADB respectively here
https://apps.aavso.org/vsp/. These are plotted to mag 10 which is probably a bit faint but will be useful if you continue following the nova as it fades. [The real reason is that I habitually plot to mag 10 for my 80mm frac and mag 12 for the 150mm frac as this is just slightly below the limiting mag of these scopes in my backyard.]
There is also news about the progenitor star here
