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 peak of Solar Cycle 25 started in January and goes through October, which means we could see more solar flares in the coming months. Solar flares decrease as the sun nears solar minimum. So ...
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 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 ...
May 2024 solar storms: X1.2(X1.3)-class flares [93] and X4.5-class flare. [94] The flares with a magnitude of 6–7 occurred between 30 April and 4 May 2024. On 5 May the strength of the solar storm reached 5 points, which is considered strong according to the K-index. The rapidly growing sunspot AR3663 became the most active spot of the 25th ...
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 ...
The solar storms send particles flowing from the sun that get caught up in Earth's magnetic field, causing colorful auroras to form as they interact with molecules of atmospheric gases. In the ...
Near solar maxima, the Sun produces about three CMEs every day, whereas solar minima feature about one every five days. [16] CMEs, along with solar flares of other origin, can disrupt radio transmissions and damage satellites and electrical transmission line facilities, resulting in potentially massive and long-lasting power outages.
