Substorm event at 0830UT

These THEMIS measurements correlate with Cluster observations.

Below is the GBO map. Clicking it will open a page with more ground-based data.

Below is 6-hour THEMIS observations overview. Click on the animation opens a page with stills covering 6-12 UT and satellite positions.

Below are several quantities useful for timing, from top to bottom: (1) THEMIS pseudoAE index, Pi2 pulsation at (2) Loysburg and (3) Carson City, (4) Magnetic field x component in GSM coordinate from FIT instrument, (5) Ion velocity x component in GSM coordinate from momentum calculation of ESA instrument, (6) Electric field y component in GSM coordinate calculated from vxB, (7) Electric field in GSM coordinate from EFI instrument, (8), Total pressure (larger) and magnetic pressure (smaller)
