Fiery Pegasus on the Sun during an X5.1 flare
The "Fiery Pegasus" Delivers Record Solar Blow in Current Cycle
Author: Uliana S.
On November 11, 2025, a solar event captured the immediate attention of the entire scientific community. A massive X5.15 class flare erupted on the Sun's surface, briefly creating a striking image that resembled a gigantic fiery Pegasus. While this poetic phenomenon was visually stunning, it served as a dramatic harbinger of a significant real-world threat heading directly toward Earth.

The powerful eruption, which occurred around 12:00 UTC, was immediately followed by the detection of a colossal Coronal Mass Ejection (CME). Observatories confirmed that magnetic plasma structures were simultaneously ejected into interplanetary space from three distinct active regions. Initial calculations offered a momentary glimmer of hope: the core of the ejection showed a 20-degree deviation from the direct Sun-Earth trajectory, suggesting the impact might be substantially mitigated.

However, any initial optimism quickly faded as pessimistic forecasts began to materialize. By approximately 18:00 UTC, spacecraft positioned at the Lagrange Point L1, situated 1.5 million kilometers from Earth, were bombarded by a dense cloud of solar protons. The characteristic "noise" registered on the detectors—similar to signals observed before historic geomagnetic storms—provided unambiguous confirmation: the primary, massive plasma cloud was indeed tracking directly toward our planet, leaving little doubt about the impending crisis.

The extreme nature of the event was officially confirmed by the National Oceanic and Atmospheric Administration (NOAA). Their calculations, released on November 12 around 00:30 UTC, designated this solar outburst as a record-breaking incident for the current 25th solar cycle. NOAA issued a severe warning regarding a potential preemptive strike from the solar material expected within the subsequent hours, urging preparedness for widespread disruption.
The leading edge of the first of three anticipated plasma clouds reached the L1 satellites during the morning hours of November 12. Predictions indicated this initial wave would reach Earth sometime later that day, initiating the geomagnetic disturbance. The most significant danger, however, stems from the third and final ejection associated with the X5.15 flare, which is traveling at a record velocity, making it the primary concern for infrastructure operators. Scientists are currently unable to provide precise impact predictions, cautioning that the ultimate severity hinges on whether the three distinct clouds merge into a single, massive wave during their transit across interplanetary space. Nevertheless, all predictive models concur on one critical point: the planet is bracing for an unprecedented sequence of three distinct solar impacts over a concentrated 24-hour period, with the peak intensity of this historic event projected to occur between November 12 and November 13, 2025.
