VI. Geomagnetic Activity Probabilities 30 Aug to 01 Sep

A. Middle Latitudes
Active	10%	10%	10%
Minor storm	01%	01%	01%
Major-severe storm	01%	01%	01%

B. High Latitudes

VII. COMMENTS The ACE spacecraft orbit will bring ACE to its closest approach with the Sun on August 30, 2004. During that time possible solar radio noise may interfere with spacecraft telemetry resulting in the loss of real time solar wind plasma, magnetic field, and particle data.
