SIDC Info

SIDC reports Over the past 24 hours solar activity has been quiet. No significant flares have been recorded.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar activity is expected to remain low over the next 24 hours with a chance of C-class flares.

Solar wind speed has increased from around 350 to around 400 km/s over the past 24 hours. The total magnetic field strength has increased from around 7 nT. The Bz component has ranged between -9 and +6 nT.

Finally, SIDC reports geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. The increased solar wind speeds are the result of a High Speed Stream (HSS) produced by a small coronal hole that passed the central meridian a couple of days ago, the HSS combined with elevated negative Bz may enhance geomagnetic activity over the next day.

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