Animation of a Moreton wave which occurred on December 6, 2006 Solar Tsunami. A Moreton wave, Solar Tsunami, or Moreton-Ramsey wave is the chromospheric signature of a large-scale solar corona shock wave. Described as a kind of solar "tsunami", [1] they are generated by solar flares.
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 ...
Solar activity: NASA's Solar Dynamics Observatory captured this image of the X1.2 class solar flare on May 14, 2013. The image shows light with a wavelength of 304 angstroms. Solar phenomena are natural phenomena which occur within the atmosphere of the Sun. They take many forms, including solar wind, radio wave flux, solar flares, coronal mass ...
Our life-giving death star is experiencing its "solar maximum," which sounds like the name of a Christian rock band and is defined as the peak activity period within the sun's 11-year solar cycle.
By MORGAN WHITAKER New video released by NASA Thursday captures the spectacular instant the sun fired off a solar flare in Earth's direction. The video shows the coronal mass ejection that created ...
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 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 ...
They are broad-band continuum emissions associated either with solar flares or Type I bursts. [16] Flare-associated Type IV bursts are also called flare continuum bursts, and they typically begin at or shortly after a flare's impulsive phase. Larger flares often include a storm continuum phase that follows after the flare continuum. [89]
