Activity Level on the Sun

June 15, 2019

VERY LOW — No C-class flares in the past two days.


Today's Sun!

SIDC reports solar activity was at very low levels. The solar disk was spotless. Solar activity is expected to remain at very low levels.

No coronal mass ejections (CME) were observed over the last 24 hours.

The greater than 10 MeV proton flux was at nominal values. A diffuse and fragmented negative polarity equatorial coronal hole (CH) is transiting the central meridian.

The earth environment is exiting the wind stream from the positive polarity CH. Solar wind decreased from about 475 km/s to its current 380 km/s (DSCOVR). Bz varied mostly between -4 and +3 nT. The interplanetary magnetic field was mostly directed away from the Sun (positive sector). Quiet geomagnetic conditions were observed.

Finally, SIDC reports mostly quiet geomagnetic conditions are expected. The arrival of the wind streams associated with the negative polarity CHs, currently expected for 17 June, may drive geomagnetic activity to active levels, with a minor storming episode not excluded.

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