NOAA AR 2634 evolved into a beta magnetic field configuration and is the only visible active region on the solar disk. There have been no C-class flares in past 24 h. C-class flares are possible.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 h.
Geomagnetic conditions have reached K=4 overnight due to the longlasting effect of a fading high speed stream (HSS) with speeds between 550 and 600 km/s. Solar wind speed is now at 500 km/s with interplanetary magnetic fields of 4 nT. Another HSS from a small equatorial positive polarity coronal is expected to affect the Earth within 24 h. Geomagnetic conditions up to K = 5 can be expected.
Today's estimated international sunspot number (ISN): 012, based on 08 stations.
