Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona). The plasma medium is heated to tens of millions of kelvins, while electrons, protons, and heavier ions are accelerated to near the 查看更多內容

Soft X-ray classification
The modern classification system for solar flares uses the letters A, B, C, M, or X, according to the peak flux in watts per square metre (W/m ) of soft X-rays with wavelengths 0.1 to 0.8 nanometres (1 to 8 ångströms), … 查看更多內容

Flares produce radiation across the electromagnetic spectrum, although with different intensity. They are not very intense in visible light, but they can be very bright at particular spectral lines. They normally produce bremsstrahlung in X-rays and 查看更多內容

A solar flare has been the main plot device for science fiction stories:
• Flare, a 1992 novel by Roger Zelazny and Thomas Thurston Thomas
• Inconstant Moon, a 1996 Outer Limits episode on Showtime by writer Larry Niven and starring Michael Gross 查看更多內容

Flares occur when accelerated charged particles, mainly electrons, interact with the plasma medium. Evidence suggests that the … 查看更多內容

Current methods of flare prediction are problematic, and there is no certain indication that an active region on the Sun will produce a flare. However, many properties of sunspots and active regions correlate with flaring. For example, magnetically … 查看更多內容
