It has been reported that a solar storm is heading towards Earth today, September 3, 2023. The Space Weather Prediction Center (SWPC) of the National Weather Service has issued a Geomagnetic Storm Watch for the day. On this day, Earth may experience a mild G1 level geomagnetic storm, which is the lowest level on the 1-5 scale. While it may cause some aurora displays and minor disruptions in electrical grids, navigation, and communication systems, it is not expected to be a severe event, according to spaceweather.com.

The Current Geomagnetic Activity

On September 2nd, the Space Weather Prediction Center (SWPC) reported a minor G1-class geomagnetic storm caused by a high-speed solar wind stream. This stream is generated by the Sun when it releases massive amounts of energy out into space. It’s worth noting that this solar storm is different from the two Coronal Mass Ejections (CMEs) that are currently heading towards Earth. The first CME was released on August 30th, while the second was launched on September 1st. It is expected that the arrival of these CMEs on September 3rd may extend the ongoing storm and raise its level to G2 geomagnetic storm.

What Are Coronal Mass Ejections (CMEs)?

Coronal Mass Ejections, also known as CMEs, are massive bursts of plasma and magnetic fields that are released from the Sun’s corona. These ejections can expel billions of tons of material and carry a magnetic field that is stronger than the interplanetary magnetic field (IMF) of the background solar wind. The speed of CMEs varies, with some reaching Earth in as little as 15-18 hours, while others might take days. As these ejections move away from the Sun, they grow in size, and the larger ones can cover a significant portion of the space between Earth and the Sun by the time they reach us.

The Impact of Geomagnetic Storms

The impact of a CME on Earth’s magnetosphere depends on its energy level and angle of contact. Geomagnetic storms can cause disruptions to electronics, electrical systems, and spacecraft communication. On the other hand, they can also produce stunning aurora displays in the night sky.


Today, we are experiencing a G1-class geomagnetic storm, which is expected to cause minor power grid fluctuations in northern latitudes. There may also be minor disruptions to satellite operations, while aurora displays could extend further south than usual, possibly reaching northern Michigan and Maine.


If the geomagnetic storm intensifies, the auroras could become even more vibrant and extend further southward. However, it is important to note that this storm is expected to be mild, with minimal impacts on daily life and technology. The event is being closely monitored, and there is no need for panic or worry.
