I have found C/2020 P1 NEOWISE in STEREO A HIA on 2020 October 14. It is surprisingly still alive!
Appears about magnitude 9.5-10.
From Earth's perspective, that would translate to magnitude 8.5, which is in line with Seiichi Yoshida's predicted lightcurve.
The comet is 0.92AU from the Spacecraft, less favourable.
