Updated August 17, 2022 at 3:53 PM. A strong geomagnetic storm caused by the sun could impact Earth later this week, space weather forecasters say.
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 ...
An extreme (G5) geomagnetic storm alert was issued by the National Oceanic and Atmospheric Administration (NOAA) – the first in almost 20 years. [ 96 ] [ 97 ] The final storms reaching the highest level of NOAA's G-scale before Solar Cycle 25 occurred in 2005 in May, [ 98 ] [ 99 ] [ 100 ] August, [ 101 ] and September, respectively.
Powerful geomagnetic storms are becoming more common now that the sun has reached solar maximum, which happens when our star's poles flip, ... as was the case in February 2022, ...
February 3 – A geomagnetic storm impacted the areas around the Arctic Ocean and disrupted up to 40 new SpaceX Starlink satellites that were launched earlier in the day. [148] The storm also caused the Space Weather Prediction Center (SWPC) to issue a G1 geomagnetic storm warning. [149] February 4 – A series of avalanches killed eight people ...
Historically, G4 storms are common during a solar cycle, but G5, or extreme geomagnetic storms such the one that occurred on May 10, are incredibly rare, Dahl said. This new storm has a 25% chance ...
Geomagnetic storms can also add energy to currents in Earth's magnetic field that can increase distribution of density in the upper atmosphere and cause extra drag on low-orbiting satellites.
On 3 and 4 November, the K p index reached 8−, equivalent to a G4 geomagnetic storm. [42] This was the most intense geomagnetic storm to hit Earth since September 2017. 2022
