Extreme G5 Geomagnetic Storm Alert/ Northern Lights May 10-12, 2024
Extreme G5 Geomagnetic Storm Alert
Event dates: May 10-12, 2024
Space incident!
This is a very rare event going on the next couple of days!
We’ve just been upgraded to a G5 which means Extreme, and we knew we should send out an alert tonight!
The event can last from hours to days.
Yes, the Northern Lights can be very pretty to the eye.
However, the last G5 geomagnetic storm occurred in October 2003 and caused power outages in Scandinavia and damaged infrastructure as far south as South Africa!

World Warned to Prepare for Today’s Severe Geomagnetic Storm, First in 20 Years
Here are some excerpts:
- The National Oceanic and Atmospheric Administration has forecasted a severe solar storm to hit Earth tonight, with the potential to disrupt navigation systems and infrastructure.
- The storm was given a Severe (G4) rating, with at least five coronal mass ejections expected to hit Earth between May 10 and May 12.
- The last G5 geomagnetic storm occurred in October 2003, causing power outages in Scandinavia and damaging infrastructure as far south as South Africa.
From RSOE/ Hungarian National Association of Radio Distress-Signalling and Infocommunications:
The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center forecasted a “severe solar storm” that’s expected to hit Earth tonight, according to a release. These geomagnetic storms happen every so often, but as the Sun approaches the maximum of its 11-year solar cycle, the space weather is getting more intense.
A geomagnetic storm occurs when solar flares and coronal mass ejections (CMEs) occur on the Sun, causing variation in the solar wind that hits Earth’s magnetosphere, the protective sheath of Earth’s magnetic field.
At best, the storms cause mesmerizing—but harmless—auroras, as charged particles from the Sun collide with the particles that make up Earth’s atmosphere along its magnetic poles, emitting visible light. But at worst, the storms can disrupt Earth-based navigation systems like GPS and trigger disruptions to infrastructure like the power grid and radio and satellite communications.
The coming storm was given a Severe (G4) rating by the Space Weather Prediction Center and prompted a Geomagnetic Storm Watch, the first time since January 2005 such an alert has been issued. The center anticipates at least five CMEs that will be directed at Earth between midday today, May 10, and Sunday, May 12. The Sun produced a strong solar flare on Thursday, specifically an X1.1 flare; “X-class denotes the most intense flares, while the number provides more information about its strength,” according to NASA. Earlier in the day, NOAA documented an even stronger solar flare, classified as a strong X2.2 flare.
Here are some ways to prepare:
- Fill up your car’s gas tank in case your local gas stations lose power and can’t pump gas.
- Charge your devices and keep extra battery packs in case you are without power for an extended period of time.
- Make sure you have a way to get in and out of your house/garage if the electric garage door opener stops working.

Please know that intense solar activity
- can disrupt the body’s circadian rhythm, nervous system, heart rate and blood pressure, and
- can impact radio communications and technology.
.
Outages could decommission everything from cell phones and computers to automobiles and airplanes.
