Bulletin

Solar activity remains very low, no C-class flares in past 24 h. The active regions rotating into view over the eastern limb have simple configuration and are not elevating the flaring level. The solar wind speed is at 470 km/s with interplanetary magnetic field intensities of 5 nT. Mostly unsettled geomagnetic conditions have been recorded in the past 24 h. The arrival of a fast speed solar wind stream from a big coronal hole in the northern hemisphere is expected within 24 h. Active geomagnetic conditions can be expected with minor storm periods possible.

Today's estimated international sunspot number (ISN): 024, based on 13 stations.
