On Saturday, NOAA’s Space Weather Prediction Center (SWPC) noted that an M8.1 solar flare, “an eruption of energy from the sun that generally lasts minutes to hours,” had been detected. Considered ...

A powerful M8.1 solar flare sent a full-halo coronal mass ejection toward Earth, and scientists expect it to trigger strong G3 geomagnetic storm levels on Tuesday. Forecasts show the Kp index rising ...

A powerful solar eruption is expected to hit Earth soon, according to a forecast from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

A strong geomagnetic storm may hit Earth on Monday night after the sun released a powerful M8.1 solar flare on Saturday. The NOAA Space Weather Prediction Center issued a geomagnetic storm watch, ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

A strong G3 geomagnetic storm could cause the sky to light up where you live, although is not expected to be seen as far south as the one in November.

A geomagnetic storm watch has been issued after a powerful solar flare over the weekend. The solar flare peaked at 9:49 p.m. EST on Sunday, November 30, said NASA’s Solar Dynamics Observatory, which ...

Our sun continues to make news headlines as we’re still in a strong solar cycle that has generated numerous solar flares and coronal mass ejections (CMEs). CMEs are a large release of plasma and ...

A week after strong geomagnetic storms pushed the northern lights far beyond their usual range, fresh solar activity could make the aurora visible across much of the continental U.S. as forecasters ...

Geomagnetic storms are disturbances in Earth's magnetic field caused by solar activity, particularly from coronal mass ejections (CMEs). These CMEs release massive bursts of solar material and ...

A geomagnetic storm watch has been issued after a powerful solar flare over the weekend. The solar flare peaked at 9:49 p.m. EST on Sunday, November 30, said NASA's Solar Dynamics Observatory, which ...
