Bulletin

NOAA AR 2635 evolved into a beta magnetic field configuration but did not produce any more C-class flares, although they remain 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 been at k = 2 levels. Solar wind speed is now at 420 km/s with interplanetary magnetic fields of 4 nT. The low latitude extension of the northern polar coronal hole may affect the Earth within 48h, but it is possibly too high in latitude to do so. Quiet geomagnetic conditions expected.

Today's estimated international sunspot number (ISN): 017, based on 04 stations.
