The sun's most active phase, solar maximum, kicked off in 2024, allowing an unusually high number of powerful X-class flares to explode from our home star. | Credit: NASA/SDO/AIA/LMSAL The number ...

The Sun regularly produces solar flares, which are energetic outbursts of electromagnetic radiation. Sometimes, these flares are accompanied by plasma in events known as coronal mass ejections. Both ...

As if on cue, X-class solar flares on the sun — which are often followed by CMEs — occurred again on Friday, Jan. 3 and Saturday, Jan. 4, which could mean more geomagnetic storms into next week.

The sun fired off an X1.2-class solar flare on Friday (Jan. 3), triggering radio blackouts throughout parts of the South Atlantic ocean, Africa and South America.

which rates how the solar flare will contribute to radio blackouts and what impacts could be associated with it. The scale ranges from R1 to R5, meaning this blackout event was rated as "Strong ...

For example, if regional tensions over Taiwan should flare up, China could halt the delivery of solar panels to the U.S. and continue selling them to Europe, Africa and the Middle East.

The time to flare was analysed using the log-rank test and Kaplan-Meier methods. The percentage of patients achieving sustained remission is summarised using descriptive statistics (counts and ...
