Presentation Transcript

  1. Relatively dispersionless • particle injections span a broad range in MLT • Appear to be a “global” mode of auroral activity • Correlated with a change in the magnetic field (stretching and relaxing) at geosynch orbit over broad MLT range • Examples: • “Global” sawtooth oscillations occur at ~03:00UT, 05:45UT, 08:30UT,11:30-11:40UT • More localized in MLT after that Henderson et al., SM31B-08

  2. Characteristics of Sawtooth Oscillations
