Solar activity was very low. Region 2759 (N28, L=263) remained spotless, but active, producing low level flares early in the UTC day. There were no Earth-directed CMEs observed in available coronagraph imagery.
The solar kp index is unsettled, with retrograde effects slightly enhanced. The solar wind speed is currently above average, making retrograde effects moderately increased.
There are no planets in retrograde!
The Solar System at a Glance
Solar wind parameters were at background levels. Solar wind speeds averaged between 300-338 km/s throughout the day. Total field was 6 nT or less, and Bz was mostly not of note until late in the UTC day when it began to deviate southward in excess of -5 nT. Phi was negative.
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.
