Largest Solar Flare in a Decade Erupts; Communication Interference, Aurora Are Likely Side EffectsPhilip J. Hilts
GPS L1-L2 phase slips on October 28, 2003 Fig. 6d (black line) presents P(t) dependences for the October 28, 2003 flare on the earth sunlit side (330–120° E; –80+80° N) derived from n=2452 LOS observations, for all observable satel...

On the other hand, electron events associated with long-duration X-ray events had a characteristic single power law spectrum (Dröge, 1995a and 1995b). Charged Particle Energy Spectra The slope and shape of the energy spectrum of solar particles changes with time during a flare. The most ...
This energetic solar flare activity is very important in the first million years or so, then decreases (Feigelson et al., 2002a). From this it has been concluded that the early Sun had a 105-fold enhancement in energetic protons which may have contributed to short-lived nuclides (Lee et ...
Significant fractions of that energy go into radiation, the rest goes into heating and acceleration of particles, the partition depending on the type of flare. The different kinds of radiation come from different parts of the flare site and are released at different times of the flare process. ...

Kelvin (15 million Celsius, 27 million Fahrenheit). It's tough to describe temperatures like these in relatable terms because they're so far outside everything humans experience. The core of a star reaches temperatures—energy levels, really—we don't see anywhere else outside fusion reactors....
(1936) reported on observations that suggest the possibility of geomagnetic disturbances related to eruptive filaments (in H-alpha) outside of sunspot regions. Newton (1943) further developed this idea and established the flare—geomagnetic storm connection. In particular, he showed that the storm-...
flare site on the western hemisphere. This comparison shows that the broad longitudinal distribution of gradual events is unlikely to occur as a result of rapid coronal diffusion or cross-field transport, because such effects should also occur during the smaller impulsive SEP events. Rather, the ...
