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 During last 24 hours several B-class flares were observed, and the strongest reported flare was B9.6 (peaked at 19:31 UT on March 24), originating from the NOAA AR 2736 (no Catania numbering). This active region, which was also source of many B-class and some C-class flares during past few days, has rotated over the west solar limb. Another active region which was observed on the visible side of the solar disc during last days, NOAA AR 2735 (no Catania numbering), is presently situated at the west solar limb. We can expect occasional B-class flares in the next 24 hours, while C-class flares are still possible but not probable.

No Earth directed CME's in past 24 hous.

Solar protons remained at background values over the past 24 hours.

The in situ observations (DSCOVR) indicate arrival of the CME-driven shock wave, at about 20:43 UT on March 24. The shock observed in the solar wind was associated with the March 20 CME. The arrival of the shock wave did not induced disturbed geomagnetic conditions (local station at Dourbes and NOAA reported only K=2 and Kp=2, respectively). The solar wind speed is about 330 km/s and the interplanetary magnetic field magnitude is 5 nT.

Finally, SIDC reports geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours. The arrival of the fast solar wind, associated with the negative polarity equatorial coronal hole that is expected tomorrow, might induce unsettled to possibly active geomagnetic conditions.

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