Short summary

A new plasma intrusion or preonset aurora scenario of substorm triggering proposed by Nishimura et al. (2010) needs to be tested. To test the scenario, we revisited three of their substorm events in detail, based on THEMIS ground-based all-sky imager data. We list a series of open questions for testing the scenario further in future studies.
