No C-class flares in past 24 h, they remain possible in the next 24 h. The eastern part of NOAA AR 2651 has been numbered as NOAA AR 2652, with alpha magnetic field configuration.
No Earth directed Coronal Mass Ejections (CMEs) have been detected (but there are no coronagraph images available at the moment of writing). Solar protons have remained at background levels over the past 24 hours.
The Earth is under the fading influence of a high speed stream, with solar wind speeds around 500 km/s and interplanetary magnetic fields of 4 nT. Geomagnetic conditions ranged from K=3 to K=4 and Kp between 3 and 5 in the past 24 h. Mostly unsettled geomagnetic conditions are expected in the coming hours.
Today's estimated international sunspot number (ISN): 041, based on 19 stations.
