Bülletään

Solar flaring activity was low with only some low level C flaring from AR2403. The strongest event was a C2.8 flare peaking at 23:53UT. AR 2403 seems to stabilize and decay but there remains a likelihood for M flaring or possibly an X flare. The warning condition for proton events is correspondingly maintained. Coronagraph data show a slow eruption towards the SouthWest starting yesterday afternoon. It is not believed to have any influence on Earth. Solar wind speed stabilized at around 420 km/s while total magnetic field increased from a nominal 5nT to around 10 nT currently. Bz was predominantly negative with peaks close to -8nT. Geomagnetic conditions were quiet to active (local K Dourbes 2-3, with NOAA Kp reaching 4 for the 6-9UT and 9-12UT intervals). Solar wind conditions are expected to initially remain at these levels while increasing later tomorrow (August 27) with the expected arrival of a corotating interaction region and high speed stream. Geomagnetic conditions may reach active conditions in response.
