Bulletin

Solar activity has been very low, no C-class flares in past 24h. Two active regions visible on the disk, 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 hours.

Geomagnetic conditions have ranged between K=1 and K=2. Solar wind speed is now at 380 km/s with interplanetary magnetic fields of 4 nT. The southern extension of the northern polar coronal hole may affect the Earth within 24 h, with K values up to 5 (although it’s probably too high in latitude to affect the Earth at all).

Today's estimated international sunspot number (ISN): 032, based on 16 stations.
