Sun Unleashes Strongest Flare of 2025, Causing Global Radio Blackouts
On Nov. 11, 2025, the Sun erupted with an X5.1-class flare, disrupting shortwave communications across Africa and Europe. The flare’s X-rays and UV radiation ionized Earth’s upper atmosphere, causing R3-level radio blackouts. NOAA warned that a coronal mass ejection could reach Earth on Nov. 12, potentially triggering strong geomagnetic storms ...

Massive X-Class Solar Flare Erupts, Causing Widespread Pacific Radio Blackouts
A powerful X1.9-class solar flare from sunspot 4114 erupted on June 19, disrupting shortwave radio signals across the Pacific, including Hawaii. While it caused significant atmospheric ionisation, no coronal mass ejection (CME) followed. The event highlights rising solar activity and hints at more eruptions ahead, potentially impacting communicatio...

Qualcomm Releases Study Showing That Its Modems Beat Apple’s C1
Qualcomm's modem chips worked better than a rival component developed by Apple, a study commissioned by the former said. The iPhone 16e, the first smartphone to use Apple’s in-house C1 modem, was slower to download and upload information on T-Mobile’s 5G network in New York City than Qualcomm-powered Android devices, according to a report by Ce...

NASA Astronauts Williams and Wilmore Complete Successful Spacewalk to Remove Faulty Unit
NASA astronauts Sunita Williams and Barry Wilmore successfully completed a 5-hour and 26-minute spacewalk on January 30, 2025, to remove a faulty radio frequency group (RFG) from the International Space Station (ISS). Despite several failed attempts in 2023 and 2024, their persistence paid off, marking a significant achievement. Williams also set a...

X-Class Solar Flare From Sunspot 3912 Causes Radio Blackouts in Southern Africa
A powerful X-class solar flare erupted from sunspot region 3912 on December 8, disrupting high-frequency radio communications in southern Africa. The flare, accompanied by a coronal mass ejection (CME), ionised Earth’s upper atmosphere, absorbing radio signals and causing blackouts in areas exposed to peak solar activity. Experts predict the CME ...
