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 solar activity has been at very low levels over the past 24 hours. The Sun is currently spotless and the X-ray flux remains below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal values.

The expected enhancements in the solar environment due to the influence of the coronal hole (which has reached the central meridian on Nov 13) has arrived yesterday on Nov 16 around 17:00 UTC. The total magnetic field reached 9.5 nT at 18:00 UTC, the solar wind speed raised up to 450 km//s, and the southern component of the magnetic filed fluctuated between -7.7 nT and 9.2 nT. The enhanced solar wind conditions are expected to persist as long as the Earth remains under the influence of the coronal hole effects.

Finally, SIDC reports that while quiet geomagnetic conditions were observed with Kp-index (NOAA), quiet to unsettle conditions were observed with the local station in Dourbes (K-Dourbes = 3) in response to the solar wind enhancement. More active conditions is not excluded, especially with the slow increase of the solar wind speed and possibly longer period of southward directed Bz component.

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