The first visible and electromagnetic effects of a solar flare reach observers on Earth at the speed of light, which means they were spotted about eight minutes after they occurred on the surface ...
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 ...
The Solar Cycle 25 Prediction Panel predicted in December 2019 [11] that solar cycle 25 will be similar to solar cycle 24, with the preceding solar cycle minimum in April 2020 (± 6 months), and the number of sunspots reaching a (smoothed) maximum of 115 in July 2025 (± 8 months).
In 1943, Grote Reber was the first to report radioastronomical observations of the Sun at 160 MHz. The fast development of radioastronomy revealed new peculiarities of the solar activity like storms and bursts related to the flares. Today, ground-based radiotelescopes observe the Sun from c. 15 MHz up to 400 GHz.

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 solar cycle.
The good news is that Earth should be out of the line of fire this time because the flare erupted on a part of the sun moving away from Earth. NASA's Solar Dynamics Observatory captured the bright ...
Solar storms include: Solar flare, a large explosion in the Sun's atmosphere caused by tangling, crossing or reorganizing of magnetic field lines; Coronal mass ejection (CME), a massive burst of plasma from the Sun, sometimes associated with solar flares; Geomagnetic storm, the interaction of the Sun's outburst with Earth's magnetic field
