Abstract We use the example of two Stealth-type coronal mass ejections (stealth CMEs) registered by LASCO C2 on the quiescent Sun on 16 June 2010 and in the active region NOAA 11520 7 July 2012 to demonstrate that these mass ejections emerged in a lower-coronal area where an intense short-term radiation burst was registered in several extreme ultraviolet channels. It is established for the first time that the stealth CME emergence is accompanied by an eruption of small-scale loop-like structures, and the frontal structure (FS) formation is detected. The time dependences of the velocity of these FSs are discussed. The conclusion is made that having reached Earth orbit and impacting on the terrestrial magnetosphere, the stealth CMEs can lead to magnetic substorm generation.

隐形日冕物质抛射的源区识别及地球物理效应

摘要 我们使用 LASCO C2 于 2010 年 6 月 16 日在静止太阳上和 2012 年 7 月 7 日在活动区域​​ NOAA 11520 中记录的两次隐形型日冕物质抛射（隐形 CME）来证明这些物质抛射出现在较低的在几个极紫外线通道中记录到强烈的短期辐射爆发的日冕区域。首次确定隐身CME的出现伴随着小规模环状结构的喷发，并检测到了锋面结构（FS）的形成。讨论了这些 FS 的速度的时间依赖性。得出的结论是，隐身CME到达地球轨道并撞击地球磁层后，会导致产生磁亚暴。
