Latest update:
Severe to extreme geomagnetic storms are possible again today, meaning we may get another chance to see the Northern Lights in the Southern U.S.
The National Oceanic Atmospheric Administration’s Space Weather Prediction Center said the ongoing storm will likely become more intense later Sunday with several intent coronal mass ejections, or CMEs, expected to reach the Earth’s outer atmosphere later today. The results will be the Aurora Borealis being visible at lower latitudes tonight.
Northern Lights were reported as far south as Florida Friday night but lessening of the geomagnetic storms made Saturday night viewing harder.
Earlier:
Strong geomagnetic storms have brought the Northern Lights to people as far south as Florida. And while Saturday night’s levels have dropped, we could be in for more of a light show on Sunday.
According to the National Oceanic Atmospheric Administration’s Space Weather Prediction Center, K index values have dropped slowly today falling down to a G2, meaning the aurora displays that lit up the Alabama sky Friday night lwon’t be seen Saturday night.
However, NOAA said a secondary peak in solar storm activity is likely with geomagnetic storming of varying intensity continuing. By early Sunday and into Sunday night, the next major Coronal Mass Ejection will hurdle toward the Earth at speeds of 100 kilometers per second, slamming into the Earth’s magnetic field and reaching the outer atmosphere. That will elevate chances for more displays of the aurora borealis.
A G4 watch remains in place for May 12, though periods of G4-G5 – the highest on the scale – are possible by Sunday.
“Weather permitting, aurora will likely be visible over a large portion of the United States, NOAA said.

The brilliant nighttime displays do come with a cost, however. NOAA said there have been preliminary reports of power grid irregularities, and degradation of high-frequency communication, GPS and satellite navigation.
Additional strong solar flares and CMEs will continue until the large sunspot cluster that’s the source of the activity rotates out of view, most likely by Tuesday.
Best way to see the Northern Lights
For the best viewing, go to a dark area with as little light pollution as possible. It’s also best to go to an area away from cloud cover if possible. When you get outside, look to the north and, according to experts, a cell phone may be better for capturing images than a naked eye.
