Solar activity was very low. Region 2759 (N28, L=261) remained spotless, but did produce a few B-class flares early in the UTC day. There were no Earth-directed CMEs observed in available coronagraph imagery, although there was some activity off the East limb.
There are no planets in retrograde!
The Solar System at a Glance
Solar wind parameters were at background levels. Solar wind speeds continued on a downward trend, and were less than 325 km/s by days end. Total field was less than 5 nT, and Bz was unremarkable. Phi was highly variable between positive and negative solar sectors during the first half of the period, but has since settled into a negative orientation.
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.
