Solar Storm Watch: Geomagnetic storms possible today due to possible effects of coronal mass ejections

Solar Storm Watch: Just a few days ago, sunspot AR3559 posed the threat of an X-class solar flare due to its “beta-gamma-delta” magnetic field. The development comes as the National Oceanic and Atmospheric Administration (NOAA) releases new predictions for Solar Cycle 25. According to forecasts, the peak intensity of the solar cycle is expected to be stronger than previously expected. Now, forecasters have revealed that a coronal mass ejection (CME) could hit Earth soon and could trigger a geomagnetic storm. Learn all about solar storm warnings.

According to space weather ReportNOAA forecasters say a coronal mass ejection could pass over the Earth’s magnetic field today (March 14). This could trigger a small G1 geomagnetic storm. That said, no aurora sightings are expected.

The report states: “Today, geomagnetic activity is low and no bright auroras are expected. However, changes may be coming. NOAA forecasters say a coronal mass ejection may pass through the Earth’s magnetic field on March 14. Low-probability impact A minor G1 level geomagnetic storm may result.”

Solar activity has increased in recent weeks due to the phenomenon known as the Russell-McPherran effect. During this time, the Sun is directly above the equator, causing day and night to be of equal duration. As a side effect, there is a semiannual variation in the effective southward component of the interplanetary field. NASA says cracks forming in Earth’s magnetic field could allow even weak solar wind to penetrate. This means that even weak solar flares and coronal mass ejections can trigger geomagnetic storms and solar storms.

Are G1 geomagnetic storms dangerous?

NASA says G1 geomagnetic storms are considered small storms and won’t cause much damage. While they are not powerful enough to damage satellites or disrupt mobile networks, these geomagnetic storms can still cause radio outages.
