The event occurred in 2012, near the local maximum of sunspots that can be seen in this graph.. At 02:08 UT on 23 July 2012, a large coronal mass ejection (CME) was launched from the Sun. [3] The eruption emanated from solar active region 11520 and coincided with what was at most an X2.5-class solar flare. [4]
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
A solar flare is a sudden flash of brightness observed over the Sun's surface or the solar limb, which is interpreted as an energy release of up to 6 × 10 25 joules (about a sixth of the total Sun's energy output each second or 160 billion megatons of TNT equivalent, over 25,000 times more energy than released from the impact of Comet ...
A common measure of flare duration is the full width at half maximum (FWHM) time of flux in the soft X-ray bands 0.05 to 0.4 and 0.1 to 0.8 nm measured by GOES. The FWHM time spans from when a flare's flux first reaches halfway between its maximum flux and the background flux and when it again reaches this value as the flare decays.
Pierre-Simon Laplace, one of the originators of the nebular hypothesis. Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in the sense we now understand it, existed.
The moon will appear to move in front of the sun beginning at 2:07 p.m. on April 8 in Rochester, New York. The window of totality is just 3 minutes and 38 seconds, with variance for location, and ...
Commonly referred to as being "blown up", "blown apart", or "dashed to pieces" in older literature, [3] total body disruption may be caused by such traumas as being within or in close proximity to a powerful explosion, uncontrolled decompression, or implosion. It is the most severe type of blast injury. [4]
The Sun produces radio emissions through four known mechanisms, each of which operates primarily by converting the energy of moving electrons into electromagnetic radiation. The four emission mechanisms are thermal bremsstrahlung (braking) emission, gyromagnetic emission, plasma emission, and electron- cyclotron maser emission.
