Resolution No. 4 (2005): Continuity and rapid production of auroral electrojet indices

IAGA, noting that

  • scientific progress in understanding magnetospheric and ionospheric dynamics is adversely affected by the unavailability of the definitive auroral electrojet indices for years beginning in 1995, and,
  • the international community is anticipating active cooperation with NASA THEMIS mission which addresses physical processes monitored by these indices


  • relevant national funding agencies, research institutions and scientific investigators to invite participation from the international science community to assist in constructing recent auroral electrojet indices, and,
  • implementing a system to achieve timely production of the auroral electrojet indices, not later than the start of NASA THEMIS mission prime phase (autumn 2006).
