Every entry the map has collected for this layer, newest first. Each one is dated to when it was published, carries the subtopics it touches, and links out to its source. Click any subtopic to see only its entries.
On August 5, 2026, researchers using the Daniel K. Inouye Solar Telescope in Hawaii released unprecedented high-resolution images of the solar surface that show in fine detail how magnetic energy accumulates and…
On September 1-2, 1859, astronomer Richard Carrington watched a brilliant 'white-light' solar flare; about 17 hours later its coronal mass ejection struck Earth, producing the most powerful geomagnetic storm in…
Active Region 4479 unleashed an X1.1 flare and full-halo CME on June 30, 2026. The cloud reached Earth on July 3 and escalated to a G3 (strong) geomagnetic storm early July 4 — stronger than the G1-G2 forecast —…
In early June 2026 active region AR4455 released three significant solar flares in quick succession, and NOAA's Space Weather Prediction Center issued a G3 (Strong) geomagnetic storm watch for June 4–5.
A 2026 study released the first reproducible, systematic reanalysis of every published tree-ring radiocarbon record of Miyake events — rare, extreme bursts of cosmic radiation preserved as carbon-14 spikes — along…
Astrophysicists at the University of Warwick identified a recurring moment in each solar cycle when the most extreme space-weather activity abruptly shuts off.
Miyake events — enormous bursts of solar particles — are dated by radiocarbon spikes locked into tree rings, and they are the main evidence that the Sun can fire off storms far larger than anything modern…
In a Journal of Geophysical Research: Space Physics paper, researchers analyzed 50 years of GOES satellite data (1975-2025), catalogued 37 S-class 'superflares,' and built a model predicting extended windows when…
A study published in April 2026 in the Journal of Atmospheric and Solar-Terrestrial Physics measured Earth's Schumann resonance at 10-minute resolution from southern Spain and found its amplitude rises about 6.2%…
New Parker Solar Probe data published March 31, 2026 in the Astrophysical Journal shows that during magnetic reconnection the Sun accelerates protons and heavy ions very differently — protons spread like a…
A space-physics preprint analyzing the January-February 2026 flare storm reports that Solar Cycle 25's recent activity is the largest in roughly two decades, producing a measurable ground-level enhancement (extra…
Over roughly 24 hours starting late Feb. 1, 2026, active region AR4366 fired at least 18 M-class and three X-class flares, including an X8.3 — the strongest solar flare of 2026 so far.
In February 2026 the Sun produced an X8.3-class solar flare, the biggest recorded in 2026 and among the largest of Solar Cycle 25, even as the cycle moves past its peak yet keeps producing violent eruptions.
NASA recorded an X8.3 solar flare on February 1, 2026, the most powerful of the current solar cycle and among the strongest in roughly 20 years, followed by several more X-class flares within days.
A peer-reviewed study tracked heart rate variability in 16 participants over 31 days against simultaneous solar wind and geomagnetic field data.
A 2026 arXiv preprint analyzed observational and statistical parameters across Solar Cycle 25 and concluded that its maximum phase was not a single peak but a structured, multi-peaked stretch with unusual solar…
On January 19-20, 2026 the Space Weather Prediction Center tracked an S4 (severe) solar radiation storm — the strongest since the Halloween storms of October 2003.
