My best aurora experience took place in August, oddly enough. It was a warm night, so I went out on the deck and laid on the chaise lounge, my big cat of the time flopped out on my chest. The moon was about 3/4 full and for some reason a small prop plane was circling overhead (there’s a flight school out at the airport, probably it was from there). Then I saw the ghostly curtain of an aurora to the north. Very poetic experience.
