Bulletin

Solar X-ray flux remained below B level. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux was at nominal levels the past 24 hours.

At the start of the period a slight enhancement of Solar wind conditions has been recorded. Solar wind speed reached 400 km/s at the start of the period, returning to a nominal 350 km/s currently over the period. Total magnetic field was around 5nT with Bz variable and the magnetic field phi angle mostly in the negative sector. A further renewed enhancement of Solar wind conditions may still occur later today and into tomorrow, related to the extension of the southern polar coronal hole that transited central meridian starting April 7.

Geomagnetic conditions were quiet (NOAA Kp 1-2, local K Dourbes 0-2). Unsettled to active conditions are possible in the next 24-48 hours, should Solar wind enhancements related to the extension of the southern polar coronal hole still set through. Otherwise mostly quiet conditions are expected.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 27 Stationen.
