SIDC Info

SIDC reports NOAA AR 2671 has again increased in size and produced C-class flares, there were four in past 24 h. The strongest one did not originate in NOAA AR 2671 though, it was a C4.4 peaking at 20:02 UT on August 18 and came from a region rotating into view from the east limb. A CME erupted in the vicinity of this region (seen at 14:24 UT on August 18 by LASCO-C2), directed to the east and will not be geoeffective. C-class (and possibly M-class) flares can be expected

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The Earth is still inside a high speed solar wind stream, the speed is around 680 km/s with interplanetary magnetic field intensity of 7 nT. As a consequence, Kp reached 5 and the local K went up to 4.

Finally, SIDC reports more disturbed conditions are expected in the next 24 h.

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