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.
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 ...
A powerful solar storm due to hit the Earth on Tuesday could spark brilliant auroras. Auroras could be seen as far south as Wyoming, Wisconsin, and New York.. Expect to see more auroras in coming ...
It was classified as an X1.2 flare.X-class flares are the strongest, and powerful X-class flares have the ability to create world-wide blackouts. Solar flares are ranked by their strength, with ...
A geomagnetic storm is heading to Earth, with the possibility to disrupt GPS and communications. It could also bring the northern lights to Northern California, much farther south than is typical.
On 8 May 2024, a solar active region which had been assigned the NOAA region number 13664 (AR3664) produced an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth. [6] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME.
The incoming solar storm arose from a strong flare near “Region 3500” on the Sun, scientists say. Solar storms are known to interfere with the Earth’s magnetic field and cause damages to ...
Mercury then fractures but stays together because of the magnetism and is pushed out of its orbit, starting on a collision course with Earth. Meanwhile, in a university auditorium on Earth, scientist James Preston explains how unpredictable asteroids, solar flares, and comets are. He then describes a planetary defense system called Project Seven.
