Mezinárodní číslo slunečních skvrn :
000
Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : 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.
