14248776 - This was the view as a multi-colored curtain of aurora formed to the south in my sky during the great display of Northern Lights on May 10, 2024. The Kp Index peaked at 8 this night bringing the aurora borealis and australis to wide areas of the planet including the tropics. This was from home in southern Alberta at latitude 51° North, where the aurora filled the sky but, as here, was often best and brightest to the south. The colours come from oxygen, nitrogen and sunlight creating the shades of green, red, pink, and blue.70483023 - Shades Of Red And Orange In The Clouds At Sunset70285675 - Pre-sunrise alpenglow paints North Window and Turret Arch in brilliant shades of red in Arches National Park, Moab, Utah71162893 - Aerial View Of The Forest During Autumn In Shades Of Red And Gold Surrounding A Small Lake
