Presentation Transcript

  1. THEMIS A, B, D, & E magnetically conjugate to TPAS, ATHA, & FSIM (sites 14, 12, & 8) during magnetic activity while we have excellent ASI data from those three sites. This is a substorm event with outstanding ground coverage and excellent satellite coverage from GOES & THEMIS. Unfortunately, we only have ESA data from TH A, but we do have FGM data from all. If we have GOES 10 as well as 11, 12, there are at least seven satellites in the inner magnetosphere from which we can study the azimuthal and radial expansion of the current diversion and injection.

  2. These are one hour (0500-0600 UT) hires keograms from three stations in the region of interest. All three sites had clear skies and between them the onset region is (I think) completely covered (you can also see the onset through the clouds at FSMI as well, but I think we do not need that).

  10. Event study for GRL Special Issue and Fall AGU… Propose a straightforward study of azimuthal and radial expansion of pseudobreakup(s?) and breakup between 0500 and 0600 UT on March 13 2007. For this event we have essentially complete coverage at 3 second cadence by the ASIs (TPAS, ATHA, FSIM), and excellent magnetic conjugacy with GOES 11, 12 (maybe 10), and TH A, B, D, E (FGM on all 4 and ESA on TH A). Together with the NORSTAR/NRCan riometers, Shiokawa’s MSP at Athabasca, the NORSTAR MSP at Pinawa, the ground mag array, and the 6 satellites this may be one of the best events to date for studying the azimuthal and radial evolution of the inner magnetospheric disturbance.
