Flaring activity at the frontside of the solar disk was very low, without any C-class flares. NOAA active region 2524 (Catania 49) turned into a beta region, while NOAA 2519 (Catania 44) remained stable. All other regions decayed or even turned into plage. A filament eruption occurred around UT midnight near S10W30, but no clear related CME was observed in coronagraphic data. There is a probability of 25% for C-class flares.
The solar wind conditions indicated the continuation of the high speed stream influence. Solar wind speed has gradually decreased from 550-600 km/s to current values near 450 km/s. The magnetic field magnitude remained near 5-7 nT, with a fluctuating north-south component. A coronal hole in the northern hemisphere has crossed the central meridian, which is expected to cause a high speed stream near Earth within 2 to 3 days. Geomagnetic conditions were mainly quiet (K=0-2) to unsettled (K=3), which is expected to remain so for the next 24 to 48 hours. Though, an isolated period of active conditions (K=4) is possible.
Today's estimated international sunspot number (ISN): 040, based on 13 stations.
