Bulletin

Flaring activity has been very low, no C-class flares in past 24 h. No large flares expected, although C-class flares are possible from NOAA AR 2570 (Beta magnetic field configuration). A partial halo CME directed towards the north was first seen at 17:48 UT on July 30 by LASCO C2. This is most likely a back sided event that will not affect Earth. Quiet geomagnetic conditions were recorded in past 24 h, no changes expected. Solar wind speed is at 400 km/s with interplanetary magnetic field magnitude of 4 nT.

Today's estimated international sunspot number (ISN): 012, based on 29 stations.
