‘Severe’ geomagnetic storm sends Northern Lights to Central Florida. Can you see them?

G5 geomagnetic storm underway until Friday, Oct. 11

Hurricane Milton has come and gone, and the Northern Lights are popping up right on the storm’s heels.

According to the NOAA, a “severe” G5 geomagnetic storm watch is underway, which is forecast to last through Friday.

During this time, the Aurora Borealis has already been seen as far south as South Florida and the Bahamas.

Due to cloud cover, much of the Northern Lights have been shrouded in areas near Orlando.

However, News 6 Meteorologist Jonathan Kegges said that areas southwest of Orlando — places like Minneola, Clermont and Kissimmee — could have a better chance of catching a view.

Typical viewing for geomagnetic storm conditions

WHEN WILL THEY HAPPEN?

University of Alaska researchers predict that geomagnetic activity will be strongest around Thursday evening before gradually dropping off as we approach late Friday. As a result, this will likely be the best time for people in affected areas to see the northern lights.

Earlier this year, an intense G5 geomagnetic storm caused northern lights to blossom all the way down to South Florida.

While the storm this time around isn’t quite as strong, chances remain slim that Central Florida could get another look at them.

CAN I WATCH THEM FROM FLORIDA?

If the Aurora were to materialize in Central Florida with the current storm, it would likely be red and very low on the horizon.

While there is no guarantee the Northern Lights will be seen in Central Florida, hopeful sky watchers should allow 15 minutes for their eyes to adjust to the darkness.

Look north and low on the horizon.

A planetary K index of 9 is typically needed to catch a glimpse in Florida. As of Thursday afternoon, that value was just below 8.

Clouds will be an issue, especially along the coast, as the the stiff breeze from Milton sends moisture from the Atlantic into the peninsula.

Future clouds and rain

The best chance for breaks in the clouds will be along and west of I-4.

WHAT ARE THE AURORA BOREALIS? (NORTHERN LIGHTS)

The Aurora Borealis, commonly known as the northern lights, are vibrant dancing ribbons of light that form as a result of electrons colliding with Earth’s upper atmosphere.

The solar wind, charged protons and electrons emitted from the sun, first interacts with and significantly disturbs Earth’s magnetic field causing a geomagnetic storm.

Those particles follow Earth’s magnetic field and enter the Earth’s atmosphere at or around the poles. This is where the magnetic field is at its weakest.

How Northern Lights form

Those electrons then interact with and excite molecules in Earth’s atmosphere. The excitement of the molecules results in the production of vibrant colors in the sky.

The largest geomagnetic storms are caused by a coronal mass ejection (CME) — a large ejection of the sun’s magnetic field and plasma.
