Bulletin

Solar flaring activity was limited to three B1 flares from NOAA 2526. No earth-directed coronal mass ejections (CMEs) have been observed over the last 2 days.

Quiet conditions are expected to continue.

Solar wind speed decreased from initial values near 450 km/s to values around 400 km/s by the end of the period. Bz varied between -3 and +3 nT. The interplanetary magnetic field was directed away from the Sun till about 08UT, then slightly towards between 08-12UT. Geomagnetic conditions were quiet.

Mostly quiet to unsettled geomagnetic conditions are expected until the arrival later today or tomorrow (2 April) of a sector boundary crossing and the co-rotating interaction region ahead of the wind stream of the small negative equatorial coronal hole. This may result in minor geomagnetic storming on 2 and 3 April, with a small chance on moderate storming on 2 April.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 013, basierend auf 17 Stationen.
