Activity Level on the Sun

VERY LOW — No flares in the past two days.

SIDC reports solar activity was at very low levels. Small and inactive region NOAA 2709 (Catania 81) doubled its number of sunspots to 2.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels.

Earth remained under the influence of the wind stream from an elongated negative polarity equatorial coronal hole (CH). Solar wind speed first decreased from about 480 km/s to 420 km/s by 23UT, then started a gradual increase to values near 520 km/s by the end of the period (DSCOVR). Bz varied between -6 and +4 nT, and was predominately negative until about 04UT. The interplanetary magnetic field was mainly directed towards the Sun. Geomagnetic activity ranged from quiet to mostly unsettled levels in Dourbes, with Kp recording 3 active intervals.

Finally, SIDC reports quiet to unsettled geomagnetic conditions are expected, with a chance on an isolated active interval.

Now . . . let's take a little tour into the realm of:
