标题： Correlation of the estimated arrival time of the relativistic solar ions at 1 AU and start of ground level enhancement (GLE)

摘要： 我们研究了计算得到的首批相对论性离子到达地球的时间与地表监测器记录的太阳高能粒子增强事件（GLE）开始时间之间的可能关联。 分析基于由先进太阳分光计（ACE卫星上的SIS仪器）记录的首批太阳离子的到达时间和能量，以及由GOES卫星记录的质子数据。 我们考虑了两种情况：当首批高能离子的星际传播几乎无散射时，以及在行星际磁场中传播期间高能离子的扩散效应。 我们外推时间和速度以及时间和刚度的关系，以计算具有足够能量进入亚拉腊特地理坐标大气层并产生可被监测器探测到的次级通量的相对论性离子的预期到达时间。 显示英文摘要

摘要： We are investigated possible correlations between the calculated arrival times of the first relativistic ions at Earth and GLE start times registered by surface monitors. The analysis is based on the arrival times and energies of the first solar ions, registered by the Solar Isotope Spectrometer (SIS) on board of the ACE satellite, and protons, registered by GOES satellites. We consider both cases when the interplanetary propagation of the first high energy ions is essentially scatter-free and the diffusion of high energy ions during propagation in the interplanetary magnetic field. We extrapolate the time-velocity and time-rigidity relationships to calculate the expected arrival times of the relativistic ions that are energetic enough to enter the atmosphere at the Aragats geographical location and produce secondary fluxes that reach the monitors.
