Four solar storms headed for earth this week- Alert for stargazers

Four coronal mass ejections from sunspot AR4246 are heading toward Earth, triggering auroras across northern skies and minor satellite or power disruptions.

A set of solar storms are moving straight towards Earth with four CMEs. These storms are expected to be seen in between Oct. 15 and 17. These storms could lead to amazing auroras across northern horizons, and possibly even at mid-latitudes.

A Surprise from the Sun

Earth can expect a great display as four CMEs launched from the new sunspot region AR4246 between 11–13 October now heading towards our home planet. Scientists indicated the CMEs will arrive sometime after 15–17 October, possibly creating geomagnetic storms. These storms will provide great auroras across high latitudes.

Mild Storms, Major Displays

While the predicted storms fall under the G1 category, the mildest level on NOAA’s five-point space weather scale, they are still capable of generating impressive northern lights. Regions such as northern Michigan, Maine and northern Scotland may see skies illuminated in shades of green, pink and purple.

The Impact of CMEs on Earth

CMEs refer to significant eruptions of charged particles from the Sun as well as the magnetic field. When these collide with Earth's magnetosphere, they can generate geomagnetic disturbances.

These disturbances can have an effect on power grids and satellites in extreme instances. Because four CMEs are overlapping, they could intensify the impacts and prolong the duration of the storms over several days.

An Alert for Skywatchers

Strongest disturbances are likely late on 15–16 October, providing beautiful viewing conditions for aurora activity in high-latitude areas. Experts prefer that skywatchers observe real-time space weather to see this beautiful show.
