Saw it last night, easy naked-eye in dark skies, est vis mag 5.0 (1:00 am 17 July 2020 AEST). Great work by Rob McNaught, congratulations to him!
It's his fourth, and 33 years after his third (Nova Sgr 1987)!
Apparently it's now fading off - peak magnitude appears to have been 3.7 on 11 July, estimated from pre-discovery images. Attached are a spectrum and a few shots I took of the nova last night.
Cheers -
