SIDC reports there is one sunspot visible on the Sun (reported this morning by the Royal Observatory of Belgium). X-ray flux is still at the A level, only minor B-flares could be expected.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The greater than 2 MeV electron flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR varied between about 320 and 380 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was oriented mostly away from the Sun (positive) with a magnitude between 3 nT and 9 nT.

Finally, SIDC reports quiet conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. The solar wind coming from the low latitude extension of the northern polar coronal hole may affect the Earth in about 48 hours, causing an increase into active geomagnetic levels (K = 4).

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