The Sun emitted a strong (X-class)solar flare, peaking at 12:52 p.m.ESTon March 3, 2023.NASA’sSolar Dynamics Observatory(SDO), which watches the Sun constantly, captured an image of the event. Solar flares are massive explosions that occur on the surface of the Sun, unleashing tremendou...
NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash on the left — on Sept. 12, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in gold. Credit: NASA/SD...
The giant solar explosions of energy and light aren't over yet. Officials said on Tuesday that the sun just emitted another major solar flare –and that it's the strongest one so far in the current solar cycle. The latest flare peaked just before 1 p.m. ET, NOAA's Space Weather ...
What makes this X-classsolar flareparticularly interesting is that it erupted from 'rule-breaking'sunspotAR3784 which had already garnered the attention of solar scientists andaurora chasersdue to its strange polarity. The sunspot's polarity breaks a hundred-year-old rule, Hale's Law, whereby su...
Newly emerged sunspot region AR3697 is already making its presence known, firing off another powerful X-class solar flare as it creeps around from behind the sun's southeastern limb. Thesolar flareeruption peaked around 10:35 a.m. EDT (1435 GMT), causing shortwave radio blackouts across Wester...
Extreme ultraviolet light streams out of an X-class solar flare as seen in this image captured on March 29, 2014, by NASA's Solar Dynamics Observatory. This image blends two wavelengths of light: 304 and 171 Angstroms, which help scientists observe the lower levels of the sun's atmosphere....
It is found that the model does not fit the observations well, but does provide a well defined lower limit on a flare's total cooling time. The discrepancy between observations and the model is then assumed to be primarily due to heating during the decay phase. The decay phase heating ...
In the early morning hours of August 9, a huge solar explosion shot particles of light and energy out into space.
