This image of a colorful aurora was taken in Delta Junction, Alaska, on April 10, 2015. All auroras are created by energetic electrons, which rain down from Earth’s magnetic bubble and interact with particles in the upper atmosphere to create glowing lights that stretch across the sky.

We are well into aurora season in the northern hemisphere. Even though the Sun has been quiet regarding solar activity in 2020, auroras are still something to look forward to. We are finally climbing out of solar minimum, which means auroral activity should increase as we head towards solar maximum.
