The Solar System at a Glance
Solar wind parameters continued to reflect lessening influence from the negative polarity, south polar CH HSS. Solar wind speed decreased from ~470 km/s to end the period near 400 km/s. Total field averaged near 4 nT, the Bz component was between +/-3 nT, and the Phi angle was solidly in a negative solar sector.
There is a 10% chance of solar activity, with a 1% chance of a minor event, a 1% chance of a moderate event, and a 1% chance of a strong event.
