Solar flares decrease as the sun nears solar minimum. So, throughout the 11-year solar cycle, flares may occur several times a day or only a few times per month, according to NASA.
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
A new artificial intelligence model trained on decades of data on the Sun’s activity would have predicted the unexpected intense solar storm that struck the Earth last year, scientists say.. In ...
Sun outage times are published in local newspapers. As the majority of rural Alaska is served by satellite, population centers like Utqiaġvik , Kotzebue , and Nome suffer from this as well. Nome is the terminus of the annual Iditarod Trail Sled Dog Race , and due to its timing, announcements of the finishers are often delayed during these Sun ...
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 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.
Region 3500 on our Sun just fired a near X-class flare and launched a strong Earth-directed #solarstorm. Waiting for coronagraph imagery, but it looks like this storm could arrive by December 1.
Four solar flares occurred within 5 days from sunspot AR 12192, which is both the largest sunspot of solar cycle 24 and the largest since 1990. On October 19 there was a major X1.1-class solar flare. On October 22 an M8.7-class flare was followed by an X1.6 event. The October 24 X3.1-class solar flare was strong enough to trigger a radio blackout.
