Transcript of Relatively dispersionless particle injections span a broad range in MLT
• Relatively dispersionlessparticle 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
Characteristics of Sawtooth Oscillations
