[1]在9月9日至10日首次成功之后，He II（304 A）扫描仪于1998年9月20日至21日拍摄了等离子体的EUV图像[中村等人，2000年]。虽然地磁和太阳条件几乎相同，但在第一张和第二张图像之间，在等离子层顶外部看到的等离子总量是不一致的。这些等离子体直接从电离层填充或从等离子体屏蔽器连续泄漏。我们的结论是，即使在安静/温和的地磁条件下，等离子体泄漏的等离子体的贡献是从电离层的直接填充的贡献一样显着。
[1] The EUV imagery of the plasmasphere was taken by the He II (304 A) scanner on 20–21 September 1998 after the first success on 9–10 September [Nakamura et al., 2000]. Total amount of the plasma seen in the outside of the plasmapause is inconsistent between the first and the second images, although geomagnetic and solar conditions are almost the same. These plasmas are directly filled from the ionosphere or continuously leak from the plasmasphere. We conclude that the contribution of the plasma leakage from the plasmasphere is as significant as the contribution of the direct filling from the ionosphere even under a quiet/moderate geomagnetic condition.
