Bülletään

The Sun is still spotless, as the active region rotating into view over the east limb has shown no sunspots. It produced numerous B-class flares over the past 24 hours, with the largest being a B4.3 flare peaking at 12:42 UT on September 21. More B-flares can be expected, there are minor chances of having C-class flares.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The greater than 2 MeV electron flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR varied between about 300 and 350 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was oriented towards the Sun (negative) with a magnitude between 3 nT and 9 nT. Bz reached -6 nT.

Quiet to unsettled geomagnetic conditions (K Dourbes between 0 and 3; NOAA Kp between 0 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected for the next 48 hours. The solar wind coming from the low latitude extension of the northern polar coronal hole may affect the Earth in about 48 hours, that could lead to an increase in geomagnetic levels.
