Bulletin

No C-class flares in past 24 h. Both active regions on disk are relatively simple (Mag.Type: Alpha) and quiet. The X-ray flux is expected to remain below C level.

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 been quiet (k = 1-2). Solar wind speed is now at 310 km/s with interplanetary magnetic fields of 3 nT. A high speed solar wind stream from a negative polarity low latitude coronal hole (southern hemisphere) is expected to arrive in about 48 h. Geomagnetic conditions are expected to be quiet until then, and reach active to minor storm levels after. There is a small and weak low latitude coronal hole north of the equator, its associated fast solar wind stream may arrive earlier, although this is not likely.

Today's estimated international sunspot number (ISN): 023, based on 22 stations.
