A bright green fireball was visible in parts of the Pacific Northwest as it beamed across the sky. The Oregon Museum of Science and Industry describes a fireball as a particularly bright meteor that can be seen up to 80 miles above the Earth. The museum says green fireballs are often due to the presence of magnesium. The metal emits a bright blue-green light when it heats up upon entering the Earth’s atmosphere. Jason Jenkins saw the fireball in southwestern Washington just after 6 a.m. Monday as he was driving to work. He said his dashcam video didn’t do justice to how bright and close it seemed.
