**Northern Lights Alert For 17 States After ‘Double Eruption’ On Sun**
In a rare occurrence, the National Oceanic and Atmospheric Administration (NOAA) has issued a Northern Lights alert for 17 U.S. states this week due to a powerful G2-rated geomagnetic storm resulting from two coronal mass ejections (CMEs) on the sun.
This exceptional event is sparked by a “double eruption” of magnetic filaments, which detached from the sun’s surface and produced the CMEs. These particles will interact with Earth’s magnetic field later this week, potentially causing aurora displays in certain regions.
The 17 states at risk of witnessing this spectacular phenomenon include Alaska, Washington, northern Oregon, northern Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, northern Iowa, Wisconsin, northern Illinois, Michigan, New York, Vermont, New Hampshire, and Maine. However, it’s crucial to note that optimal viewing conditions require a dark location with minimal light pollution.
NASA’s DSCOVR and ACE satellites will provide the most accurate predictions of aurora visibility once the data is received from space. This information can be accessed through NOAA’s 30-minute forecast or by using the Glendale App.
The Northern Lights, also known as aurora borealis, are caused by the interaction between the solar wind and Earth’s magnetic field. The recent surge in solar activity, which saw eight M-rated solar flares between Friday and Monday, has led to this rare phenomenon.
As the solar wind accelerates, it is expected that a Kp index of 6 will be reached, indicating “bright and active” aurora displays. While the exact timing and visibility are difficult to predict, we can expect to see an enhanced auroral display.
