The biggest flare we've ever seen from the sun occurred in November 2003 and is rated as X45," Stephen Drake, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement. "The flare on DG CVn, if viewed from a planet the same distance as Earth is from the sun, would have been roughly 10,000 times greater than this, with a rating of about X100,000

Really cool and interesting.

They can get larger--as in what is seen what with variable stars.

Part of me wonders if that is due to a companion, but perhaps not.

No, really hot.

The eruption's temperature reached 360 million degrees Fahrenheit

Yes, such as FG Sagittae, V838 Monocerotis, V605 Aquilae and V4334 Sagittarii. Fits in perfectly with stellar theory. /s
