Activity Level on the Sun
September 12, 2018
VERY LOW — No flares in the past two days.
SIDC reports solar activity was very low. A new emerging active region NOAA AR 2722 (Bxo, Beta) has some potential to produce C-class flares.
No earth-directed coronal mass ejections (CMEs) were observed.
The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low.
Solar wind parameters variations decreased after the passage of the co-rotating intercation region. Solar wind speed decreased from about 590 to 530 km/s. The total interplanetary magnetic field is below 6 nT. Bz varied between -3 and +5 nT.
Finally, SIDC reports geomagnetic conditions gradually decreased from the moderate storm level yesterday till quiet conditons observed now. Geomagnetic conditions are expected to be mostly quiet from now.
