The May 2-3, 1986 CDAW-9C interval: A sawtooth event

We re-examine the CDAW-9C interval and show that it was a sawtooth event - and therefore that sawtooth events have been studied as substorms in the past. We also show that tail-like stretching of the magnetic field can occur well inside of geosynchronous orbit and we present evidence that substorm-associated tail reconnection can occur inside of -11 R-E. We conclude that a major difference between sawtooth and non-sawtooth substorms is that the sawtooth variety appear to represent a 'mode' of behavior in which substorm activity is brought anomalously close to the Earth for extended periods of time.
