Auroras are the fascinating, even enchanting, outcome of geomagnetic storms on Earth! These stunning captivating displays of light in the night sky occur at the northern and southern poles with spectacular views of the dancing lights. These auroras are mainly caused by the solar winds in space, basically charged particles from the Sun, which accelerate through the field lines of the Earth's magnetic field. NASA says, " Auroras are created when fast-moving, magnetic solar material strikes Earth's magnetic bubble, the magnetosphere. This collision rattles the magnetosphere in an event called a geomagnetic storm, sending trapped charged particles zooming down magnetic field lines towards the atmosphere, where they collide brilliantly with molecules in the air, creating auroras. Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind."
But what happens when two different kinds of auroras merge together? This rare phenomenon captured by an amateur astronomer is something unusual in the world of auroras!
Photographer Alan Dyer from Canada started filming this unusual double aurora as soon as he spotted the dancing lights overhead. The strangest combination of red and green auroras visuals is something that he had never seen before. However, at a glance of this rare double aurora, it looks like a celestial watermelon! "A nice widely-seen Kp5 #Aurora last night, July 22-23, obscured by clouds. But I was lucky to see anything at all as the prospects for any clearing looked poor. Some nice red and magenta pillars in this display. From home in the south,” Alan said
