Geomagnetic storms are expected to buffet the Earth again on Sunday evening, following Saturday’s storms which created stunning auroras, sparking awe among skywatchers and astronomers alike.
As seen on Saturday, the storms, generated by eruptions on the Sun’s surface and fluctuations in the solar wind interacting with the Earth’s magnetosphere, have the potential to create stunning natural light displays visible at high latitudes, also known as the Northern and Southern Lights.
According to The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, a second peak in the G4 or Greater Geomagnetic Storm “remains likely.”
It predicts the next series of very fast-moving “Coronal Mass Ejections moving at speeds of up to 1,800 kilometers (1,120 miles) per second, will slam into Earth’s magnetic field,” leading to further geomagnetic storms of varying intensity, from severe through to extreme. The center says that the storms will continue into Monday of next week.
While geomagnetic storms are a natural phenomenon, they can have significant impacts on modern technology. Satellite communications, GPS systems, and power grids are particularly vulnerable during these events. Intense geomagnetic activity can induce electric currents in power lines, potentially leading to blackouts and equipment damage.
The recent surges in solar activity are beautiful to watch, but have prompted precautionary measures from space agencies and power grid operators.

Elon Musk posted on his platform X, formerly Twitter, on May 11 about how the storms are affecting his Starlink satellites. He said:
“Major geomagnetic solar storm happening right now. Biggest in a long time. Starlink satellites are under a lot of pressure, but holding up so far.”
Space agencies and power grid operators are closely monitoring the situation and taking precautionary measures to mitigate any potential disruptions.
Despite the potential challenges posed by geomagnetic storms, many are eagerly anticipating the opportunity to witness the beauty of auroras that may result from the increased solar activity, particularly if they missed them on Saturday night.
For enthusiasts hoping to catch a glimpse of the auroras, astronomers recommend heading to locations with clear, dark skies away from light pollution. When the storms are strong as in this case, auroras can be widespread and seen at lower latitudes.
Experts advise taking a picture of the skies even if you are unable to see the auroras with the naked eye as often the phone’s camera picks them up. Additionally, keeping an eye on space weather forecasts can help enthusiasts maximize their chances of witnessing this celestial spectacle.
