Hi David,
Yes, it’s nice to see this star active again. I’ve had it rsing from 12.7mv on Sep 15 to 11.8mv by Oct 8, with 0.5 mags of that in the last five days.
The VSS doesn’t have a chart for V426 Sge (also known as VEND47), but you can download one from the AAVSO web site and configure it to your type of telescope.
