An M3-class solar flare that lasted about 3 hours created a massive coronal mass ejection. The Solar Dynamics Observatory (SDO) and the Solar and Heliospheric Observatory (SOHO) captured the fireworks ...

Scientists have found that coronal loops could help predict solar flares. NASA’s Solar Dynamics Observatory captured this image of coronal loops above an active region on the Sun in mid-January ...

Solar flares occur when the sun's magnetic field -- which creates the dark sunspots on the star's surface -- twists up and reconnects, blasting energy outward and superheating the solar surface.

Solar flares are nothing new to Earth and we have experienced quite a few this year, but this weekend the sun let out a coronal mass ejection which is something a bit different. On Saturday, the ...

Periods of G3 (Strong) geomagnetic storms are likely on 16 Sep 2024 due to coronal hole influences and the anticipated arrival of a CME associated with an X4.5 flare at 14/1529 UTC from AR3825 ...

In May 2024, the largest solar flare since 2017 was detected, ranking at an X-8.7 magnitude. Then in 2025, a flare May 13 was classified as an X-1.2, and another the next day was listed as an X-2. ...

Meta description: The sun released over 50 X-class solar flares in 2024, here we take a look at the 10 most explosive events. ... This flare also produced a coronal mass ejection, ...

A coronal mass ejection from an X-5 class flare that erupted on New Year's Eve, the strongest flare of solar cycle 25, will likely trigger geomagnetic storms when it hits Earth today (Jan. 2).

The researchers suggest that observing the ultraviolet brightness variations in coronal loops can predict future solar flares two to six hours ahead of time with 60 to 80 percent accuracy, which ...

How fast does a coronal mass ejection travel vs. a solar flare? A CME can reach speeds of almost 1,900 miles per second. At that speed one can reach Earth in about 15 to 18 hours.
