ISS gains sun-watching telescope as Russians complete 6-hour EVA

Two Russian cosmonauts spent about six hours outside the ISS installing the Solntse-Teragerts sun-observing telescope on the Zvezda module, retrieving a semiconductor film sample from Nauka, inspecting a Kurs antenna, and completing multiple tasks. The telescope is designed to observe strong solar flares and run through 2028, while Kud-Sverchkov’s total spacewalk time rises to 12h11m and Mikaev records his first EVA; the outing also marked Energia’s 80th anniversary for Roscosmos.

Twin X-class solar flares trigger radio blackouts on Earth, NASA says

NASA reports two X-class solar flares within seven hours—X2.4 on April 23 and X2.5 on April 24—that knocked out radio signals on Earth’s dayside and likely accompanied by CMEs. While the sunspot’s position makes a direct Earth impact unlikely, forecasters say a glancing CME could bring geomagnetic activity and possibly auroras as paths are monitored.

Solar Storm Puts Artemis 2 Launch Window at Risk

A Sun X1.4 flare from active region 4405 triggered a radio blackout and a coronal mass ejection heading toward Earth, prompting a G2 geomagnetic storm watch as Artemis 2’s launch window nears; NASA says there’s an 80% chance of favorable conditions on Wednesday, but CME timing could delay the mission if communications or navigation are affected.

Solar Flare Timing: A Speculative Link to Earthquake Occurrence

A Japanese study models the Earth’s crust and ionosphere as a coupled electric system to explore whether solar flares could subtly influence when a fault reaches rupture. The authors stress they are discussing timing, not energy, and acknowledge the idea is preliminary and contested by experts, with further validation planned.

Sun storms could jostle Earth’s faults, new study hints at quake link

A new study suggests that solar flares may perturb Earth’s ionosphere, altering electrostatic forces in the crust and potentially nudging faults toward earthquakes. The authors model the crust and ionosphere as connected like a leaky battery; critics say the approach is oversimplified and real geology could dampen any effect. Validation is challenging, though the researchers cite a 2024 Japan quake as possible support, emphasizing that correlation does not equal causation.

Sun Unleashes Quartet of Flares, Foreshadowing a Wild Week for Space Weather

The Sun erupted four strong X-class flares from sunspot cluster RGN 4366, including an X8.1—the most powerful since October 2024—potentially boosting energetic particle events and coronal mass ejections. CMEs can illuminate auroras but also disrupt satellites, power grids, and communications. Forecasters say more “exciting activity” could be on the way as the Sun remains unusually active during its 11‑year cycle, even though overall activity is expected to wind down later this decade.

Sun Blasts Four X-Class Flares, Hinting at More Turbulent Space Weather

Four X-class solar flares (X1.0, X8.1, X2.8, X1.6) erupted from sunspot group RGN 4366 on Feb 1–2, 2026, signaling lively space weather with potential energetic particle events and possible coronal mass ejections. Forecasters say more activity could follow as the active region evolves, with potential impacts on satellites, communications, and power grids if Earth-directed CMEs occur.

Growing Sunspot 4366 Sparks Flares, CME Watch Continues

NOAA reports that sunspot group RGN 4366 has grown into a complex region capable of producing flares from M1 to X1, but no coronal mass ejections (CMEs) have been observed yet. The region remains the primary feature to watch during the week of 1–7 February 2026. Current NOAA space weather scales show minor radio blackout risks (R1) with HF radio degradation on the sunlit side.

Record-Breaking Solar Activity Unveiled by Recent Observations

A record-breaking study revealed that the giant sunspot AR 13664, which grew to 15 times Earth's width, produced nearly 1,000 solar flares, including powerful X-class flares, and triggered Earth's most intense geomagnetic storm in over 20 years, highlighting the sun's immense power during solar maximum.

Solar Orbiter Breaks Records with Extended Observation of Active Sunspot Region

Scientists used the Solar Orbiter to observe the active solar region NOAA 13664 for 94 days, the longest ever recorded, which helped link a major geomagnetic storm in May 2024 to solar activity, providing new insights into solar behavior and its impact on Earth.

Airbus Addresses Software and Solar Radiation Issues Affecting Flights

Airbus recalled thousands of A320 aircraft due to potential data corruption caused by intense solar radiation, which could affect flight control systems, following an incident where a plane experienced a sudden altitude drop. The issue is linked to solar flares and sunspot activity, prompting software updates and raising concerns about space weather impacts on aviation safety.

Sun unleashes powerful X-class flares, disrupting signals and sparking auroras

The sun emitted two powerful X-class solar flares on Nov. 4, causing radio blackouts across the Americas and Pacific, with potential for geomagnetic storms and vibrant auroras later this week, as solar activity remains high and future eruptions are possible.

Scientists Uncover the Mystery Behind 'Rain' on the Sun

Scientists have long struggled to explain the rapid formation of 'solar rain'—cool, dense plasma blobs that fall during solar flares. Recent research shows that allowing elemental abundances, especially low FIP elements like iron, to vary in models explains the quick cooling and condensation observed. This new understanding improves the accuracy of solar models, helping to better interpret solar activity and predict space weather effects.
