Activity Level on the Sun

February 19, 2019

Very LOW — No flares in the past two days.

SIDC reports solar activity was at very low levels. The 15-degrees long filament in former active region NOAA 2733 is stable and currently located near N10E15. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) have been detected.

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

Solar wind speed showed a generally declining trend from 370 km/s at the beginning of the period to 330 km/s at the end (DSCOVR). Bz ranged between -3 and +3 nT. The interplanetary magnetic field was predominately directed towards the Sun (negative sector). Geomagnetic activity was at quiet levels.

Finally, SIDC reports mostly quiet geomagnetic conditions are expected until the arrival of the co-rotating interaction region and wind stream from the positive polarity coronal hole later today or on 20 February. This may result in active conditions, with a small chance on an isolated minor storming episode.

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