The one I saw was a definite rose color, it looked as though it was rising out of the trees at the end of the road...it got so bright that on a moonless night, you could see the road, the trees on either side, a deer crossing the highway half a mile on down...
I’d love to see the lights again, but Alaska is so far away.
One of my aurora photographs many years ago actually made a magazine cover, but the aurora is so feeble anymore that it’s not worth it to set up camera and tripod, and the city lights overwhelm everything anyway. Besides, you don’t have to go to Alaska to see what is left of the aurora. There is also Greenland.
