Indices and Estimated Geophysical Parameters
AE: 100 nT avg, Peak value of ~ 400 nT at ~ 02 UT,
Polar Cap Voltage: 30 kV (avg), Hemispheric Particle Power: 5 GW (avg),
Joule Heating: 10 GW (avg)
Magnetosphere
Plasmasphere refilling began, typical of quiet times and
indicative of weak magnetospheric convection (MPA),
low ion pressure in plasmasheet (MPA), low penetrating energetic
particle background (MPA), night-side magnetosphere field line
orientation unusually dipolar (MPA), energetic particle drift
orbits unusual (SOPA), high energy electrons present at
geosynchronous orbit (MPA, LANL MPA and SOPA Team,
J. Borovsky and M. Thompson). High energy electrons present
at geosynchronous orbit (GOES, H. Singer).
Normal outer radiation belt relativistic electron distribution,
No significant flux variations (SAMPEX and GPS) no data
(X. Li and T. Cayton)
Inner Plasmasphere
Ionosphere
DMSP and NOAA particles indicate contracted and irregular oval
(Data: F. Rich and D. Evans, Interpretation: D. Knipp)
Minor disturbance indicated by southern hemisphere ionospheric
sounders at ~02 UT, then unusually quiet(P. Wilkinson).
All ground magnetic observatories indicate quiet conditions after
02 UT. South Pole Station riometer quiet (T. Rosenburg and
A. Weatherwax).
Cross polar cap voltage
remained near 30 kV (D. Knipp, B. Emery)
