This is an incomplete list of candidate substorms that occurred during THEMIS major (when all 5 spacecraft are aligned) and minor (when P2, 3, and 4 are aligned) conjunctions.

Substorm identification is based on:

Real-time AE Index Daily Plots ( http://swdcwww.kugi.kyoto-u.ac.jp/ae_realtime/index.html )

THEMIS AE Index (http://themis.ssl.berkeley.edu/summary.php)

Substorms are identified by the current Tohban. The list is complied from events identified in the Tohban Reports
