The Information Study of Solar Flare Events on November 3, 2013 and August 9, 2011

Propagation of the solar particles and its interplanetary environment of an impulsive fiare on November 3, 2013 and gradual flares on August 9, 2011 were studied. The impulsive flare and the gradual flare had the X-ray classes of M5.0 and X6.9 at the position on the Sun of S12W16 and N17W69, with the solar wind speed 387.8 km/s. and 600 km/s respectively. The shock wave after the explosion from the gradual flare was found. The propagation of the solar particles were simulated by the Ruffolo 1995, 1998 transport equation and solved by finite different method. The injection duration was estimated by the curve-fitting technique of piecewise-linear least square with the simulated results and the data from spacecraft. The solar particles with high energy transported along the interplanetary magnetic field line longer than that of the low energy solar particles. The injection duration of solar particles with high energy from the Sun to the Earth is shorter than that of the low energy. Shock wave affected on the particle acceleration after explosion in the interplanetary medium, corresponding to the long injection time. The violent explosion of these solar flares didn’t affect on the Earth’s magnetic field, because their Kp-index values were less <3.
