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 Catania sunspot group 46 (NOAA active region 2673) remained active with 4 M flares recorded over the period. The largest was an M3.7 flare peaking at 11:04UT. As this region approaches the limb in the next day, further M flaring must be expected over at least the next 24 hours, with also a significant chance for another X flare. No Earth directed CMEs are visible in coronagraph data.

Solar proton flux levels are for the >10MeV protons still above the event threshold of 10pfu, but values are decreasing. As Catania group 46 (NOAA active region 2673) remains to be active and is located favourably in terms of magnetic connection to Earth, possible renewed increases in proton fluxes must be anticipated over the next days.

Solar wind saw the final stages of the passage of the September 6 CME. At the start of the period total magnetic field steadily declined from around 17nT to a nominal 5-6nT. Bz, starting the period at a very pronounced -16nT, remained pronounced negative throughout this decline in magnetic field strength. Solar wind speed dropped steadily from around 760km/s to around 680km/s. Solar wind may remain slightly elevated under the possible influence of the negative polarity coronal hole in the southern hemisphere.

Finally, SIDC reports geomagnetic conditions started the period at moderate to severe geomagnetic storm levels (local K Dourbes 6, NOAA Kp 8) associated to the prolonged period of pronounced negative Bz values. From September 9 onwards only quiet conditions were reported. Quiet to unsettled geomagnetic conditions are expected over the next days.

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