Abstract

The maximum energy of a solar flare is found using a model of particle acceleration in a magnetic X-singularity. Based on a comparison of this model with observed extreme events, it was determined that flares with the highest possible energy have already been observed. These include events of 1859, 1940, 2003, which had an X-ray class of X40 ± 5 (according to the GOES classification). In this case, the maximum flare energy in the modern era does not exceed 5 × 10³² erg, and such powerful flares occur at intervals of about 70 years.

现代太阳耀斑的最大能量

太阳耀斑的最大能量是利用磁x奇点的粒子加速模型得到的。根据该模型与观测到的极端事件的比较，可以确定已经观测到具有最高可能能量的耀斑。其中包括1859年、1940年和2003年的事件，其x射线等级为X40±5（根据GOES分类）。在这种情况下，现代耀斑的最大能量不超过5 × 1032尔格，这种强大的耀斑大约每隔70年发生一次。
