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)
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)
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)
