A solar flare from a sunspot region associated with this activity and preceding this period produced the then largest flare detected during the Space Age at about X20 (the first event to saturate spaceborne monitoring instruments, this was exceeded in 2003) but was directed away from Earth.

Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
The Sun has unleashed a powerful solar flare, Nasa has said. The flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which ...
The first CME scheduled to reach our planet on New Year's Eve is likely associated with a recent M2 solar flare. The CME left the sun on Sunday at 1 a.m. ET, according to SpaceWeatherLive .
The first visible and electromagnetic effects of a solar flare reach observers on Earth at the speed of light, which means they were spotted about eight minutes after they occurred on the surface ...
NASA's Solar Dynamics Observatory captured the bright flash of the X-ray flare. It was the strongest since 2005, rated on the scale for these flares as X8.7. Bryan Brasher at NOAA's Space Weather Prediction Center in Boulder, Colorado said it may turn out to have been even stronger when scientists gather data from other sources.
The sun produced its biggest flare in nearly a decade Tuesday, just days after severe solar storms pummeled Earth and created dazzling northern lights in unaccustomed places. “Not done yet ...
