G2 (Moderate) geomagnetic storm conditions were observed on July 17 at 12:42 pm ET (1642 UTC due to continued activity from a coronal mass ejection that arrived on July 16.
After a coronal mass ejection from the sun hit Earth’s magnetic field on Sunday (July 16), space weather forecasters predict that geomagnetic storms may cause some intense auroras this evening (July 17).
Conditions of moderate geomagnetic storms could be seen as far south as 60 degrees latitude, according to a statement by the Space Weather Prediction Center run by the National Oceanic and Atmospheric Administration. The class G2 magnetic storm (a moderate storm) was triggered by solar particles ejected from a coronal mass ejection on Friday (July 14), SWPC officials said in an update.
According to the website Spaceweather.com , which regularly tracks space weather events, observers across parts of Canada and as far south as the northern U.S. states of Washington, Wyoming and Minnesota may be able to see auroras from the amplified displays. Auroras are typically visible near Earth’s polar regions. They are known as as aurora borealis in the Northern Hemisphere and aurora australis in the Southern Hemisphere. But during geomagnetic storms, the auroras can be amplified and be visible from a wider region. In fact, Spaceweather.com reported that visibility in the Southern Hemisphere was even better than in the north, with auroras visible in New Zealand. [The Best Places to See the Northern Lights ]
