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 the Sun produced no flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 5%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in 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 solar wind speed as registered by DSCOVR decreased from about 420 to 375 km/s in the past 24 hours. The Interplanetary Magnetic Field was predominantly oriented away from the Sun and its magnitude varied between about 3 and 6 nT. Bz was never below -5 nT. Nominal solar wind conditions are expected on May 19 and 20.

Finally, SIDC reports quiet to unsettled geomagnetic conditions (K Dourbes between 0 and 3; NOAA Kp between 0 and 1) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on May 19 and 20. Active intervals (K Dourbes = 4) are possible on May 21, due to the expected arrival of a weak solar wind stream associated with a recurring, negative polarity equatorial coronal hole.

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