| Zusammenfassung |
| The location of magnetic reconnection in the mid-tail during a substorm was studied in many researches. Here we present multi-point THEMIS observations of a reconnection event in the near-Earth magnetotail during substorm. In this event, THEMIS probes stayed in the near-Earth and mid-tail region aligning along magnetotail. This allows reconnection evolution to be probed simultaneously from about -10 RE to -23 RE down tail. The Hall current related electron streams were observed at the same time by two probes far away from reconnection site. Before near-Earth reconnection involved tail lobe magnetic field, the reconnection site was restricted in inner of -23 RE. When reconnection involved into tail lobe region, the reconnection site started to retreat gradually. |
