Bulletin

Solar activity has been very low, no C-class flares in past 24 h. Two relatively simple (alpha and beta magnetic field configuration) 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 330 km/s with interplanetary magnetic fields of 4 nT. The southern extension of the northern polar coronal hole may affect the Earth today, with K values up to 4 (although it is probably too high in latitude to affect the Earth at all).

Today's estimated international sunspot number (ISN): 027, based on 11 stations.
