The best ones are the ones that happen in the summer when you can stand or lay down outside and enjoy them without getting frostbite!
My best aurora viewing experience was August 1968 Northern Wisconsin standing in a grassy field just after sunset. It was white, pulsing and coruscating (a word I will probably never use again!) and covered half the evening sky!
Ooh I wish I’d been there. Now you made me have to look up coruscating.
Wow!
“flashing and sparkling”.
