CURRENT SPACE WEATHER

Definition

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

SIDC Info

SIDC reports NOAA 2731 produced a B1.0 flare in the past 24 hours, and has decayed to an alpha region. The chance for a C flare in the next 24 hours is estimated at 5%.

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

The greater than 10 MeV solar protons 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 300 to 350 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 0 and 4 nT. Bz was never below -5 nT. A weak solar wind stream associated with a negative polarity, equatorial-South polar coronal hole may arrive near Earth on December 16.

Finally, SIDC reports quiet geomagnetic conditions (K Dourbes between 0 and 1; NOAA Kp between 0 and 1) were registered in the past 24 hours. There is a chance for active intervals (K Dourbes = 4) on December 16 and 17, related to the possible arrival of a weak solar wind stream associated with a negative polarity, equatorial-South polar coronal hole. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on December 18.

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