There was an interesting sky show over Ørsta, Norway on March 25, 2023. An auroral activity (related to proton aurora) lasting from about 21.14 to 22.07 local time.
Patches, and blobs, of greenish light flickered and traversed the sky. A fascinating sight.

The phenomenon carries several names in scientific nomenclature, but is often called IPA, an abbreviation for Isolated Proton Arc.
