Japan’s Crimson Aurora Signals Space Storms Stronger Than Official Metrics

Japan’s Crimson Aurora Signals Space Storms Stronger Than Official Metrics

New research finds red auroras over Japan extending to 500–800 km during moderately intense storms, higher than usually expected and suggesting standard indices may underestimate storm strength. The ASYM-H index often peaks 1.3–2.0 times SYM-H, implicating solar wind density (not just speed) as a key driver for mid-latitude auroras and atmospheric heating. Findings, aided by citizen scientists, have practical implications for satellite operations in low Earth orbit due to atmospheric drag and improved space weather forecasting.

NASA wraps up ISS-based AWE mission mapping Earth's weather ripples into space weather

NASA's Atmospheric Waves Experiment (AWE) on the International Space Station has completed its data-collection phase, surpassing its planned two-year mission by gathering more than 80 million nighttime infrared images of atmospheric gravity waves generated by severe weather, showing how these waves propagate upward to influence space weather and potentially disrupt satellites and communications; AWE will be replaced on the station by CLARREO Pathfinder, and all observations will be publicly available for researchers and citizen scientists.

Vega C Delivers EU–China SMILE Space Weather Satellite Into Orbit

A European-Chinese space weather mission SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) launched on May 18 atop a Vega C rocket from Kourou, deploying into a 707 km circular orbit about 56 minutes after liftoff. Over the next ~25 days SMILE will perform 11 engine burns to place the spacecraft into a highly elliptical orbit up to roughly 121,000 km above the North Pole and 5,000 km above the South Pole. SMILE’s four instruments (UVI, LIA, MAG on the platform and SXI on the payload) will study how the solar wind affects Earth’s magnetosphere to improve understanding of solar storms and space weather. The Chinese Academy of Sciences leads the satellite platform and three instruments, while ESA provides the payload module and will assist with orbit operations. The mission is planned for three years. Vega C, ESA’s 115-foot-tall rocket debuting in 2022, now has seven flights; Avio operates this first Vega C mission.

ESA-China SMILE Mission to X-ray Earth’s Magnetosphere During Solar Storms

A joint ESA-Chinese mission named SMILE will launch to study how solar storms interact with Earth's magnetosphere by capturing X-ray emissions—the first such observations—from a highly elliptical orbit that will reach up to 121,000 km above Earth. Equipped with an X-ray imager, UV imager, ion analyzer and magnetometer, SMILE aims to improve space-weather understanding for satellites, astronauts and power grids over an initial three-year mission.

Three CMEs Could Spark a Northern Lights Show Across the U.S. Tonight

Three CMEs Could Spark a Northern Lights Show Across the U.S. Tonight

Three coronal mass ejections are racing toward Earth and could produce glancing geomagnetic storms over the next few days, raising the odds of seeing the northern lights across parts of the northern United States tonight and possibly into May 20. If conditions peak at G1, viewers in Alaska, Washington, Montana, North Dakota, Minnesota, Michigan and Maine may spot auroras; with a stronger G2, Idaho and New York could join the show. Most CMEs will miss Earth, but lingering solar wind from a coronal hole could boost geomagnetic activity. The best viewing window is a few hours around local midnight in clear, dark skies away from light pollution, though visibility remains unpredictable depending on magnetic field alignment.

Mars Atmosphere Reveals Earth-like Zwan-Wolf Effect Under Solar Storms

NASA’s MAVEN mission has for the first time observed the Zwan-Wolf effect—an Earth-originated phenomenon where charged particles are squeezed along magnetic flux tubes—in Mars’ ionosphere during a large solar storm, a finding published in Nature Communications that suggests space weather can influence the Red Planet’s upper atmosphere and may operate at low levels even without a global magnetic field, with implications for atmospheric loss and insights for other unmagnetized worlds like Venus.

Geomagnetic Wind May Bring Northern Lights to Michigan and Maine This Weekend

Geomagnetic Wind May Bring Northern Lights to Michigan and Maine This Weekend

A fast solar wind from a coronal hole could trigger a G1 geomagnetic storm tonight through May 17, boosting aurora chances across the northern U.S. and potentially allowing sightings as far south as Michigan and Maine, with strongest activity between 11 p.m. and 2 a.m. EDT. Visibility depends on cloud cover and darkness; if conditions align, look to dark skies and consider aurora forecasts for real-time updates.

Sun's 19-Day Radio Burst Sets New Record, Tracked Across the Solar System

NASA and international spacecraft tracked a 19-day Type IV solar radio burst—the longest ever observed—originating from a helmet streamer in the Sun's outer atmosphere. The event, likely powered by a sequence of three coronal mass ejections, kept electrons trapped and replenished, extending radio emissions well beyond typical durations. Observations from Parker Solar Probe, Solar Orbiter, STEREO, and Wind allowed near-continuous monitoring as the Sun rotated, offering new insights for forecasting space weather and understanding large-scale solar magnetic structures.

Sun unleashes massive flare as Earth faces CME and potential Northern Lights displays

A massive solar flare produced a coronal mass ejection (CME) traveling toward Earth at roughly 650 km/s. The CME is expected to pass by Earth, possibly with a glancing impact late on May 12–13 UTC, potentially triggering auroral displays and light shows across northern latitudes. Met Office and NOAA are monitoring the situation, noting patchy UK cloud but the chance of Northern Lights across northern Scotland and similar latitudes.

Sun Erupts M5.7 Flare; Auroras Expected Across High Latitudes This Week

A powerful M5.7 solar flare on May 10 released a CME that mostly misses Earth but could graze our planet, raising the chance of northern lights across high latitudes in the coming days. NOAA and the UK Met Office forecast a weak geomagnetic storm around May 13 as sunspot regions AR4436 and AR4432 evolve, with potential for more activity and even X-class flares in the near term.

STORIE Mission Aims to Map Earth's Hidden Ring Current from the ISS

NASA and the U.S. Space Force are launching the STORIE mission to image Earth's ring current from the International Space Station, using energetic neutral atom measurements to reveal how this doughnut-shaped particle belt forms and evolves during solar storms, with the goal of better space-weather forecasts and protecting satellites and power infrastructure.

From dolphins to space weather: six science stories you might have missed

Six science stories you might have missed span: dolphins’ speed is linked to large vortex rings generated by tail movements, with smaller vortices being byproducts of turbulence; Roman ship repairs are traced through pollen in coatings, revealing mid-voyage maintenance and trade routes; a full soda can buckles in a predictable ringed pattern due to the liquid inside; the Twelve Apostles’ formation is younger than thought and records climate-related erosion over millions of years; mushrooms’ electrical signaling is modulated by urine; and researchers use medieval records with carbon-14 dating to identify milder historical space-weather events like solar proton events.
