On 9 October, a M1.6 class solar flare erupted sending a coronal mass ejection that hit Earth on 12 October, triggering a (moderate) G2 geomagnetic storm. [39] The second X-class flare of the solar cycle erupted on 28 October, producing a CME and a S1 solar radiation storm. [40]
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 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 ...
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 recent ...
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.
Solar cycle expectations for 2025. The year 2024 was huge for solar news. In April, a total solar eclipse was visible to millions of Americans, which was then followed by multiple widespread ...
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.
NASA’s Solar Dynamics Observatory captured this image of a solar flare on Oct. 1, 2024. NASA had a busy start to October, as the agency announced that the sun emitted several major solar flares ...
