2004年2月24日，卫星STSAT - 1观测到地球内外电子辐射带之间的缝隙区被能量为100 - 400 keV的准捕获电子所填充。这次注入持续了几个小时，发生在非风暴时间的次风暴期间。这似乎是第一次观测到没有发生在地磁风暴期间的槽区电子注入。我们还报告了NOAA - POES和CPMN磁场观测站对这一事件的多仪器观测结果，并考虑了可能解释这一现象的物理机制。
The slot‐region between Earth's inner and outer electron radiation belts was observed on 24 February 2004 by the satellite STSAT‐1 to be populated by quasi‐trapped electrons of energy 100‐400 keV. This injection lasted for several hours and took place during a non‐stormtime substorm. This appears to be the first observation of a slot‐region electron injection that did not occur during a geomagnetic storm. We also report multi‐instrument observations of this event from NOAA‐POES and CPMN magnetic observatories, and we consider physical mechanisms that may account for the phenomenon.
