Abstract
Geomagnetic and solar storms and their occurrence rate with respect to the solar activity cycle is an important topic of space environment research. The minimum of solar activity during the solar cycle number23 (SC-23) have detectable effects on the space environments, where the monthly mean of sunspot number and solar proton events effecting the space environment and produced many of Geophysical effects. A detailed study of the centers of activity produced the proton events are carried out. The electromagnetic emissions at the different bands during the impulsive phase of the flare are tabulated and discussed. The different Geophysical effects due to the events are studied. Conclusions about the proton solar events at minimum activity are presented.
