Solar Orbiter Watches Sun's Most Hyperactive Region For Record 94 Days: "Milestone In Solar Physics"
The region was monitored from its birth on the far side of the Sun on April 16, 2024, until its decay after July 18, 2024.

Sun Erupts with Triple Solar Flares After Weeks of Silence
After a 22-day period of solar calm, the Sun unleashed three M-class solar flares on August 3–4, 2025, all originating from active sunspot region AR 4168. These moderate flares released intense radiation, capable of briefly disrupting high-frequency radio signals and potentially sparking auroras at high latitudes. Scientists also detected likel...

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...

X-Class Solar Flare From Emerging Sunspot Causes Radio Blackouts
An unexpected X1.1-class solar flare erupted from sunspot AR4046, triggering shortwave radio blackouts over North and South America. The flare originated from the sun’s eastern limb and was accompanied by a coronal mass ejection that is not expected to impact Earth. Space weather experts have warned that the sunspot will face Earth in the coming ...

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 ...

Massive Earth-Facing Sunspot Rapidly Increases in Size, May Result in Auroras
In what could result in some magnificent auroras or Northern Lights, a spot on the surface of the Sun has been growing at a rapid pace and has become three times the size of Earth. The sunspot, Active Region 3038 (AR3038), has been found to be facing our planet and can probably emit some solar flares. The sunspot expanded more than double in size i...
