Solar storm warning: Coronal mass ejection is about to trigger a geomagnetic storm, which may cause beautiful aurora

Solar Storm Warning: On March 17, a large coronal mass ejection (CME) erupted from the surface of the sun. This coronal mass ejection is now heading toward Earth, and it could soon trigger a geomagnetic storm, raising the potential threat of a solar storm. Just a few days ago, another coronal mass ejection passed through the Earth’s magnetic field, triggering a small G1 geomagnetic storm. Learn all about solar storm warnings.

According to a report from SpaceWeather, NASA’s Solar Dynamics Observatory recorded a massive eruption from the sun’s surface in which a coronal mass ejection was expelled. This coronal mass ejection is known as the “Canyon of Fire.” The space agency modeled the data and showed that this solar storm cloud is now approaching Earth. As a result, forecasters have issued a solar storm warning as this coronal mass ejection is now expected to pass through Earth’s magnetosphere. On March 20, it may trigger a G1 level geomagnetic storm.

In addition, reports also indicate that this geomagnetic storm may produce aurora at high latitudes, especially on the first night of northern spring.

This time of year, due to spring’s The Russell-McFerran effect, where even a small impact from a coronal mass ejection can trigger a geomagnetic storm.”

This effect occurs when the Russell-McPherran effect comes into play. During this period, even slight solar winds have the potential to trigger geomagnetic storms. But why does this happen?

About the Russell-McPherran Effect

The Spring Equinox has now arrived and the Russell-McPherran effect is beginning to kick in. During this time, the Sun is directly above the equator, causing day and night to be of equal duration. At the same time, semiannual variations in the effective southward component of the interplanetary field were also observed. This causes cracks in Earth’s magnetic field, into which even weak solar wind can penetrate and trigger solar storms.
