Researchers offer look central engine powering solar flare
2020/7/31
In a U.S. National Science Foundation-funded study published in Nature Astronomy, an international team of researchers has presented a new, detailed look inside the "central engine" of a lar...
Height structure of X-ray, EUV and white-light emission in a solar flare
Sun: fl ares – Sun: X-rays, gamma-rays – Sun: radio radiation – Sun: UV radiation – Acceleration of particles
2011/10/11
The bulk of solar flare emission originates from very compact sources located in the lower solar atmosphere and seen in various wavelength ranges: near optical, UV, EUV, soft and hard X-rays, and gamm...
Extremely Energetic 4B/X17.2 Flare and Associated Phenomena
Sun: Flares coronal mass ejections reconnection
2010/9/16
We observed 4B/X17.2 flare in Hα from super-active region NOAA 10486 at ARIES, Nainital. This is one of the largest flares of current solar cycle 23, which occurred near the Sun’s center and produced ...
Photospheric, Chromospheric and Helioseismic Signatures of a Large Flare in Super-active Region NOAA 10486
Solar flares flare trigger ring diagram
2010/9/16
NOAA 10486 produced several powerful flares, including the 4B/X17.2 superflare of October 28, 2003/11:10 UT. This flare was extensively covered by the Hα and GONG instruments operated at the Udaipur S...
