Bulletin

Solar activity was low, no C-class flares in past 24 h. NOAA 2697 has decayed from beta to alpha magnetic field configuration, no significant flares are expected in the coming hours.

Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed.

Solar wind speed is at 430 km/s with interplanetary magnetic field magnitude of 3 nT. Geomagnetic conditions reached active levels (K = 4) overnight due to the mild effect of the solar wind emanating from equatorial diffuse coronal holes (speeds reaching only 460 km/s and interplanetary magnetic field 9 nT). Quiet to unsettled conditions can be expected in the next 48 h.

Today's estimated international sunspot number (ISN): 000, based on 09 stations.
