Mezinárodní číslo slunečních skvrn :
000
Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Active conditions expected (A>=20 or K=4)
Sluneční protony : Quiet
Komentář : 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. 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 activity is expected to remain at very low levels.
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.
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.
