Very low solar activity continued despite additional development in Region 2759 (N28E38, Hrx/alpha). Region 2759 evolved further, gaining rudimentary penumbra; however, the spot group remained in a simple unipolar configuration with very weak shear. 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 the waning influences of an isolated, negative polarity CH HSS. Total IMF strength was weak at 2 to 4 nT and the Bz component underwent mainly weak deviations. Solar wind speed unsteadily decreased from ~500 km/s to near 425 km/s. The phi angle was predominantly negative.
There is a 25% chance of solar activity, with a 10% chance of a minor event, a 1% chance of a moderate event, and a 1% chance of a strong event.
