Bulletin

Solar activity was low with X-ray flux remaining below C Level. All the regions on the visible disk are fairly simple, NOAA AR 2558 can produce C-class flares. Two partial halo CMEs occurred in past 24h. The first one on June 20 at 16:36 UT (first seen by LASCO/C2) was backsided, the second one at 04:36 UT today was very slow and originated from NOAA AR 2553 close to the western solar limb (W70), no geomagnetic consequences are expected. Solar wind speed is at 400 km/s. The interplanetary magnetic field intensity at 4 nT. Geomagnetic conditions have been quiet. Active conditions can be expected for the next 48 h, due to a high speed stream from a coronal hole.

Today's estimated international sunspot number (ISN): 023, based on 12 stations.
