Satellite and model fusion boosts China solar radiation forecasts
Tokyo, Japan (SPX) Dec 31, 2025 The intermittent output of solar power creates challenges for grid operators who must keep supply and demand in balance. Traditional numerical weather prediction models often handle cloud initialization poorly, which degrades ultra-short-term solar irradiance forecasts over time. Researchers Min Chen and Liangchen Guo of the Institute of Urban Meteorology at the China Meteorological Administration have built a 0-6 hour ultra-short-term global horizontal irradiance forecasting system for China by c ... read more |

Proba-3 mission closes gap in inner solar corona monitoringBerlin, Germany (SPX) Dec 19, 2025 Proba-3 has spent its first year in orbit generating more than 50 artificial solar eclipses, giving scientists sustained access to the inner solar corona that previously could only be studied interm ... more 
Sun boundary map tracks shifting Alfven surface over solar cycleCambridge, MA (SPX) Dec 14, 2025 Astronomers have assembled the first continuous, two-dimensional maps of the outer edge of the Sun's atmosphere, tracing the boundary where the solar wind escapes the Sun's magnetic control. By comb ... more 
NASA's Parker Solar Probe Spies Solar Wind 'U-Turn'Greenbelt MD (SPX) Dec 14, 2025 Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the Sun in December 2024 have now revealed new details about how solar magnetic fields res ... more 
PUNCH mission delivers sweeping new view of solar activityLos Angeles CA (SPX) Dec 17, 2025 After less than a year in orbit, NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission, built and led by Southwest Research Institute, is returning wide-field images that place the ... more |

Stereo solar campaign links Inouye and Solar Orbiter data on tiny 'campfires'Los Angeles CA (SPX) Dec 12, 2025 The Sun is not just a glowing ball in the sky. From large magnetic loops hundreds of times larger than Earth, to tiny features that blink in and out of existence, our home star is far more dynamic t ... more 
Auroral radio signal offers new insight into intense magnetic stormsSouthampton, UK (SPX) Dec 05, 2025 A University of Southampton team has identified a distinct low frequency radio signature that appears when small-scale auroral structures known as auroral beads emerge, providing a new clue to how i ... more 
Solar telescope captures flare rich sunspot region in fine detailBerlin, Germany (SPX) Nov 28, 2025 Scientists using the GREGOR solar telescope in Tenerife have obtained a rare series of high resolution observations of the active region NOAA 14274, a sunspot group that generated two X class solar ... more 
NJIT scientists track recent solar flare disruptions in Earth's ionosphereNewark, NJ (SPX) Nov 25, 2025 Recent measurements recorded by NJIT's new network of radio telescopes show how a rare sequence of intense flares from Nov. 9 - 14, including an X5.1 event marking 2025's strongest flare so far, jol ... more
Plasmasphere compressed by recent geomagnetic superstorm dramatically slowed recoveryTokyo, Japan (SPX) Nov 21, 2025 Researchers have detailed how a geomagnetic superstorm on May 10-11, 2024, shrank Earth's plasmasphere, a protective zone of charged particles, to just one-fifth of its normal size. The event, named ... more |

Newly detected radiation in near-Earth space fades with rising solar activity
Berlin, Germany (SPX) Nov 20, 2025 Scientists from HSE University and the Space Research Institute of the Russian Academy of Sciences analyzed ERG (Arase) satellite data collected over seven years, revealing details of the hectometric continuum, a type of radio emission in near-Earth space first identified in 2017. The hectometric continuum occupies a frequency range of 600 - 1700 kHz and occurs at altitudes of one to two Earth radii, where Earth's magnetic field influences charged particle motion. Ground detection of this radiatio ... read more 
Haystack scientists study recent geospace storms and light showsBoston MA (SPX) Nov 15, 2025 The northern lights, or aurora borealis, one of nature's most spectacular visual shows, can be elusive. Conventional wisdom says that to see them, we need to travel to northern Canada or Alaska. How ... more |

Solar storm brings new chance of vivid auroras, signal disruptionsWashington (AFP) Nov 13, 2025 Spectacular displays of auroras at abnormally low latitudes were expected again Wednesday night into Thursday, a result of intense solar activity which also carries risks to communication networks. ... more 
ESA actively monitoring severe space weather eventParis, France (ESA) Nov 13, 2025 On 11 November 2025, an intense solar flare was observed, peaking around 10:04 UTC. Less than an hour later, a coronal mass ejection (CME) was detected, with an initial speed of approximately 1500 k ... more 
2025's strongest solar flare triggers global radio blackoutWashington DC (UPI) Nov 11, 2025 Scientists said the sun erupted Tuesday morning, unleashing a strong X5.1-class flare in an intense outburst, causing communications disruptions. ... more 
Our Solar System Is Moving Faster Than ExpectedBielefeld, Germany (SPX) Nov 14, 2025 How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astr ... more 
First comprehensive altitude mapping of blue aurora at 200 kilometers using hyperspectral imagingTokyo, Japan (SPX) Nov 06, 2025 Researchers at the National Institutes of Natural Sciences have established a new method to determine the altitude distribution of blue aurora using a single hyperspectral camera. Inspired by labora ... more |
