Vibrant aurora borealis displays possible due to series of solar flares

A geomagnetic storm watch has been issued for the auroral zone from 8 p.m. EDT on Thursday, June 4, through 10 a.m. EDT on Friday, June 5, as solar activity is expected to impact Earth's magnetic field.

The watch follows a series of solar flares and coronal mass ejections (CMEs) observed on June 2 and 3. Some of the ejected solar material may be directed toward Earth and could arrive between June 4 and 5, potentially causing disturbed geomagnetic conditions.

Geomagnetic storms occur when charged particles from the Sun interact with Earth's magnetic field. These events can enhance auroral activity, increasing the likelihood of seeing the northern lights across parts of Canada and other northern regions.

Forecasters expect active to stormy conditions in the polar region over the next 24 hours. The auroral zone is forecast to experience unsettled conditions, while sub-auroral areas are expected to remain mostly quiet with occasional unsettled intervals.

The strength and timing of the storm will depend on the speed and magnetic orientation of the incoming solar material once it reaches Earth.

Skywatchers in northern areas may see more widespread and vibrant displays of the northern lights.
