Bulletin

Solar activity is still low, but the background X-ray flux has slightly increased due to the active region that is in the course of rotation to the visible side of the Sun. During last 24 hours one weak B-class flare was reported. We expect the low level of solar flaring activity to persist in the coming hours, with B-class flares expected and C-class flares possible but not very probable. During last 24 hours no Earth directed CMEs have been observed and the solar protons remained at background level. The solar wind speed is about 440 km/s and the interplanetary magnetic field magnitude presently amounts 4 nT. Small equatorial coronal hole of negative polarity has reached central meridian this morning. The associated fast solar wind is expected to arrive at the Earth on May 6. The geomagnetic conditions are presently quiet to unsettled (local station at Dourbes and NOAA reported K=3 and Kp=2, respectively) and we expect them to stay so in the coming hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 17 Stationen.
