IMAGE/Electrojet locations

We recommend to use a more sophisticated method to calculate equivalent currents:
1D method
2D method
We do not any more update the results given below.

Method of characteristic points of the ground X profile

An example
Upper panel: main flow region of the eastward (EEJ - red) and westward electrojet (WEJ - blue).
Lower panel: local AU (red) and AL (blue) indices.
Curves are slightly smoothed.
Quiet time baselines are visually selected for each day.

Average locations: 1995 - 1996 - 1997 - 1998 - 1999 - 2000 - 2001 - 2002 - 2003 - 2004 - 2005

Details and an alternative approach are described on IMAGE/BEAR pages.

These plots are only for quick-look purposes!
