Northern lights could be visible in Missouri and Illinois Monday night
Key Points:
- NOAA's Space Weather Prediction Center has issued a Severe Geomagnetic Storm Alert, marking the strongest geomagnetic storm in over 20 years impacting Earth tonight.
- The aurora has been visible in some areas despite the interplanetary magnetic field (IMF) currently remaining north; a southward shift of the IMF could enhance visibility of the northern lights in the northern sky.
- Clear skies over the bi-state region of Missouri and Illinois increase the chances of seeing the northern lights, though visibility depends on the fluctuating orientation of the IMF.
- The geomagnetic storm is caused by a coronal mass ejection (CME) from the sun on January 18, which interacts with Earth's atmosphere to potentially create auroras.
