Unprecedented Solar Storm Paints Sky with Pumpkin-Colored Auroras

A recent solar storm caused a rare mix of red and green lights to fill the sky above Canada, creating a haunting pumpkin-colored aurora. The image captured by an aurora photographer shows vertical pillars of light that stayed glowing for over 20 minutes. While orange auroras are theoretically possible, they are usually overwhelmed by other colors. The last time such vibrant pumpkin-like hues were seen was during the Halloween storm of 2003, the most powerful solar storm in modern records.
