Bulletin

Solar activity has been very low, no C-class flares in past 24 h. NOAA AR 2612 rotated yesterday over the east limb and has alpha magnetic field configuration. There is one more AR rotating into view in the next day. 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 500 km/s with interplanetary magnetic field intensity of 10 nT. The Earth is still inside a high speed stream from a coronal hole. Geomagnetic conditions have reached active levels overnight at planetary levels (Kp=4), but KDourbes reached only 3. Active geomagnetic conditions (up to up to minor storm levels) can be expected in the next 48 h.

Today's estimated international sunspot number (ISN): 012, based on 11 stations.
