Bülletään

Solar activity was low during the past 24 hours, with only two C1-class flares. The last one was a two-ribbon flare and occurred at 7h30 UT near active region Catania 83 (NOAA 1755), but currently no associated CME is detected. C-class flaring conditions are expected for the next 48 hours. The solar wind speed decreased during the past 24 hours from 800 to 550 km/s. The interplanetary magnetic field is stable with a magnitude of less than 5 nT and a positive Bz-component. Geomagnetic conditions are quiet (local K<3 at Dourbes) and are expected to remain so for the next 24 hours. At the end of day 2 we expect the arrival of a fast solar wind stream emanating from a coronal hole in the central of the solar disk, possibly resulting in geomagnetically active to minor storm levels (K= 4 to 5).
