‘s Space Weather Prediction Center issued a Severe (G4) Geomagnetic Storm Watch for the evening of Friday, May 10, 2024, following a series of solar flares and coronal mass ejections (CMEs) that began on May 8. 

Space weather forecasters say that additional solar eruptions could cause geomagnetic storm conditions to persist through the weekend.

A large sunspot cluster has produced several moderate to strong solar flares since Wednesday at 5:00 am ET. 

At least five flares were associated with CMEs that appear to be Earth-directed. SWPC forecasters will monitor NOAA and NASA’s space assets for the onset of a geomagnetic storm.

Aurora Borealis (Northern Lights) Forecast May 2024

Geomagnetic storms can also trigger spectacular displays of aurora on Earth. A severe geomagnetic storm includes the potential for aurora, also known as Northern Lights, to be seen as far south as Alabama and Northern California, according to NOAA’s space weather forecasters.

Space Weather Impact On Down On Earth

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and cell phones, according to NOAA,

Sunspots Can Be Seen With Eclipse Glasses

The susnpots are big enough to be seen without a telescope but with eclipse glasses.

Sun Approaching Solar Maximum

NASA says that solar events will continue to increase as we near solar maximum in 2025, and our lives and technology on Earth, as well as satellites and astronauts in space, will be impacted by the space weather.

Solar Cycle 25 is expected to peak with 115 sunspots in July 2025.

Visible-light images from NASA's Solar Dynamics Observatory show the Sun at solar minimum in December 2019 and the last solar maximum in April 2014. Sunspots freckle the Sun during solar maximum; the dark spots are associated with solar activity. Credits: NASA's Solar Dynamics Observatory/Joy Ng


Solar Flare Strength

The solar flare is classified as as an X1.1 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
