SIDC Info

SIDC reports solar activity was at very low levels. While rounding the west limb, NOAA 2738 produced 4 B-class flares, the strongest being a B8 flare peaking at 00:50UT. The lone sunspot group currently visible on the solar disk, NOAA 2739, was quiet and is decaying. No earth-directed coronal mass ejections were observed over the last 24 hours. Solar activity is expected to remain at very low levels.

No earth-directed coronal mass ejections were observed over the last 24 hours.

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

Solar wind speed was fairly steady between 300 and 350 km/s (DSCOVR). Bz varied between -4 and +6 nT. The interplanetary magnetic field was mostly directed away from the Sun (positive sector) until about 07:00UT, when it switched back to towards the Sun (negative sector). Geomagnetic conditions were at quiet levels, with an isolated unsettled interval (14-17UT) recorded at Dourbes.

Finally, SIDC reports quiet geomagnetic conditions are expected to continue, with a chance on an unsettled interval.

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