Visual suspect confirmed

Hi Patrick

Through some cloudy conditions, I've been able to visually confirm this nova suspect at mag 12.0 on Sept 15.493.  Just waiting for it to now go into VSX!

PNV J17370958-3510211 - Now Has A Sequence

The two existing fainter comps shown on an E scale chart have been updated to match the rest of the sequence origin.

I have been sitting on this for ~24 hours in hopes that I could both improve and extend fainter.... unable to locate suitable data at this time.

Per Ardua Ad Astra,
