The National Space Weather Program wrote, "Space weather refers to conditions on the Sun and in the space environment that can influence the performance and reliability of space-borne and ground-based technological systems, and can endanger human life or health."1

VERY LOW — No flares in the past two days.
SIDC reports over the past 24 hours solar activity has been quiet. No significant flares have been recorded. All Active Regions (AR) have shown low levels of activity.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares.
The solar wind speed has fluctuated between 340 and 370 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 0.7 nT and 4 nT. The Bz component was largely positive, fluctuating between -1.2 and +3 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. A positive polar coronal hole is currently positioned in the Western hemisphere of the Sun and the resulting high-speed stream (HSS) may enhance solar wind speeds later today and as a consequence may increase geo-activity levels.
Finally, SIDC reports geomagnetic conditions are expected to be quiet to unsettled.
Now . . . let's take a little tour into the realm of:
