Solar wind conditions were indicative of continued CH HSS influences, with a short-lived enhancement in the IMF. Total IMF strength was at 7-8 nT early in the period, decreased to less than 5 nT, but strengthened again after 09/1500 UTC and reached 7-8 nT again. The Bz component varied, with a few periods of prolonged southward deviation - a maximum south deviation reached -8 nT about 09/0311 UTC. Solar wind speed fluctuated considerably between mainly 500-600 km/s (however, some questionable RTSW data was evident), with a late decrease below 500 km/s. The phi angle indicated HCS proximity as it shifted between sectors. There is a 40% chance of solar activity, with a 15% chance of a minor event, a 1% chance of a moderate event, and a 1% chance of a strong event.
