Due to intense solar activity, the National Oceanic and Atmospheric ( NOAA ) Space Weather Prediction Center ( SWPC ) has issued a geomagnetic storm warning for July 30 through August 1. If the projected G3 problems materialise, auroras may become apparent across mid-latitudes around 50°. According to NOAA SPWC, auroras have been emitted from southern Illinois and Oregon as a result of prior magnetic storms of this magnitude.
On July 29 at 8.27 pm EDT ( 0027 on July 30 ), the first of several incoming coronal mass ejections ( CMEs ) impacted Earth’s magnetic field, triggering a minor geomagnetic storm.
In response to a blog from NWS Riverton about auroras seen as far north as Wyoming, US during the solar wind, room temperature physicist Tamitha Skov responded to the comments on X,” This is an optimistic start to the various storm train we are expecting over the next few days.”
A number of potent M-class solar flares that erupted over the weekend, along with a number of coronal mass ejections ( CMEs ), are the source of the geomagnetic storm warning. The first two CMEs merged, forming a” savage CME” that is clearing a way for at least two more CMEs following behind it, according to Spaceweather.com. Although the precise date is unknown, the CMEs are scheduled to arrive between July 30 and August 1.
Ion-like electrically charged particles are carried through space by coronal mass ejections ( CMEs ). Magnetic storms can be created when CMEs meet with the Earth’s magnetic field. Throughout these situations, the particles interact with ambient chemicals, emitting energy in the form of lighting. The northern hemispheres experiences the aurora borealis, while southern hemisphere experiences the aurora terra.
NOAA uses a G-scale to classify the intensity of geomagnetic storms, ranging from G1 ( minor ) to G5 ( most extreme ). A G3-class storm is anticipated for July 30 and G2 periods for July 31 according to NOAA’s existing magnetic storm watch. The G-scale is used to categorize the potential impact and strength of these magnetic events.
