Bulletin

Solar activity has been very low, no C-class flares in past 24 h. NOAA AR 2612 remains the only visible AR, it has alpha magnetic field configuration. Solar activity is expected to remain low, but C-class flares are possible.

Proton levels are low and there were no Earth directed CMEs in past 24 h.

Solar wind speed is at 620 km/s with interplanetary magnetic field intensity of 5 nT. The Earth is still inside a high speed stream from a coronal hole. Geomagnetic conditions have been unsettled in past 24 h. Similar conditions can be expected for the next 24 h as the influence of the fast solar wind stream fades.

Today's estimated international sunspot number (ISN): 030, based on 06 stations.
