Flaring activity has been very low, no C-class flares in past 24 h. There are two active regions on the visible solar disc, Catania 13 (no NOAA number) that emerged close to disk center yesterday and Catania 14 (NOAA AR 2570) that rotated over the east limb. No large flares expected (although C-class flares are possible). A filament erupted close to disk center starting around 16:00 UT on July 28, it produced a slow and faint CME directed to the southwest first seen at 22:36 UT on LASCO C2. This CME could have an Earth directed component, that could reach the Earth on August 2. Unsettled to active geomagnetic conditions were registered in the past 24 h, due to the effect of a high speed stream that reached 600 km/s with magnetic field intensities up to 20 nT (without long periods of negative Bz). Solar wind speed is still high, at 600 km/s, with interplanetary magnetic field magnitude of 5 nT. Unsettled to active conditions are expected for the next 48 h.
Today's estimated international sunspot number (ISN): 021, based on 23 stations.
