Solar activity remained very low despite the emergence of a new sunspot group, Region 2759 (N28E51, Axx/alpha). The region was severely foreshortened, so a reliable magnetic analysis was not possible; however, it did appear to be a simple unipolar group with a positive polarity lead spot. No Earth-directed CMEs were observed in available coronagraph imagery.
The solar kp index is quiet, with no changes to retrograde effects. 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 indicative of continued negative polarity CH HSS influences. Total IMF strength decreased during the period from a maximum of 8 nT to 1-2 nT. The Bz component was variable most of the period, with several periods of prolonged southward direction and a maximum deviation of -6 nT. Solar wind speed ranged primarily from 450-530 km/s. The phi angle was predominantly negative.
There is a 30% chance of solar activity, with a 15% chance of a minor event, a 5% chance of a moderate event, and a 1% chance of a strong event.

Fun Fact About Mercury
A day on the surface of Mercury lasts 176 Earth days, but a year on Mercury takes only 88 Earth days!
