Bulletin

Solar activity has been very low, no C-class flares in past 24h, an active region rotating into view from the eastern limb may increase activity.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

Geomagnetic conditions have ranged between K=2 and K=3. Solar wind speed is now at 390 km/s with interplanetary magnetic fields of 5 nT. There is a small equatorial coronal hole that could still affect the Earth today, but K is not expected to go above 4.

Today's estimated international sunspot number (ISN): 011, based on 12 stations.
