Northern lights could be visible this weekend on the horizon

A strong G3 geomagnetic storm watch is in effect this weekend which could bring the auroras back to the lower Midwest. This display will likely not be as brilliant as the gorgeous auroras we saw months ago, but some glow may be visible on the northern horizon the next few nights.

The geomagnetic storm this weekend is the result of a strong solar flare that occurred on Thursday around noon. This solar flare was rated an X9.0, the strongest since 2017! While not all solar flares lead to a coronal mass ejection (CME), a CME was detected with this flare. CMEs increase the chances of seeing the northern lights.

Back in May of this year, a G4 geomagnetic storm produced a radiant display of auroras for central Missouri. This weekend's event is forecast lower at a G3 which usually only provides a faint glow on the horizon for the Midwest. This is still a rare chance to see the northern lights this far south and weather conditions are quiet and favorable for viewing the night sky locally. For the best views of the auroras, head away from city lights and look toward the northern horizon. The further north you are will provide better viewing potential.
