NASA’s Solar Dynamics Observatory captured this image of a solar flare on Oct. 1, 2024. NASA had a busy start to October, as the agency announced that the sun emitted several major solar flares ...
A severe geomagnetic solar storm could bring colorful auroras to the night sky across parts of the nation for a third night in a row. The auroras could be seen as far south as Alabama and west to ...
A large solar flare and a fast-moving coronal mass ... a severe geomagnetic storm warning was issued as a result of the ejection at 11:41 a.m. EDT and G3 (strong) conditions were seen at 11:49 a.m ...
On March 10, 1989, a huge solar flare caused a storm that surged the Quebec power grid, which was out of commission for eight long hours on a weekday morning, affecting about 6 million people.
A solar, or geomagnetic, storm occurs when the charged particles within solar wind interact with Earth's magnetic field, causing a significant disturbance, according to NASA.
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25. The geomagnetic storm was the ...
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a corotating interaction region (CIR), a high-speed stream of solar wind originating ...
The U.S. National Oceanic and Atmospheric Administration issued a rare severe geomagnetic storm warning when a solar outburst reached Earth on Friday afternoon, hours sooner than anticipated.
