I've created the following animation of images centered on where a major nova burst occured in 1901 from DSS image plates (shot over a time span of decades) to create this 2 frame animation of the expanding shell of hot gas (moving >1200 km per hour)

I learned of this variable from the AAVSO website, as nowadays Nova Persei 1901 is known to variable star observers as GK Persei, with very regular outburst or flare-ups in brightess approximately every 3 years, you can see a chart of this at

and here's a Wikipedia article on it
