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.
On August 16, 1989, [16] another storm caused a halt of all trading on the Toronto Stock Exchange when three redundant disc drives all failed. [17] Since 1996, geomagnetic storms and solar flares have been monitored from the Solar and Heliospheric Observatory (SOHO) satellite, a joint project of NASA and the European Space Agency (ESA).
Superflares are extremely strong solar flares -- explosions with energies up to ten thousand times that of typical solar flares. ... “High-energy particles can permanently damage processors ...
Caused by an X8-class solar flare aimed directly at Earth Apr 2001 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 ...
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 flare was rated an R3-strength (flares are rated R1-R5, with R1 being the weakest) by NOAA, meaning that it may cause a "strong" radio blackout. "Today's X9 (R3) flare was prolific, but ...
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 powerful solar flare has been hurled out of the Sun, and could cause disruption on Earth.. The flare comes amid increasing solar activity that has brought a run of intense space weather in ...
