Bulletin

Solar activity has been very quiet, no C-class flares in past 24 h. An active region rotating into view over the east limb will likely change the situation. C-class flares can be expected.

Proton levels are low and there were no Earth directed CMEs in past 24 h.

Solar wind speed is at 450 km/s with interplanetary magnetic field intensity of 5 nT. Geomagnetic conditions have reached active levels overnight (both locally and at planetary levels). This is because of the moderately fast winds (reaching 530 km/s) from a coronal hole. The shape of the coronal holes present on the disk is highly irregular, so fast speed streams are expected to appear intermittently in the next 48 h. Geomagnetic conditions up to up to minor storm levels (with possible isolated major storm periods) can be expected.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 011, basierend auf 09 Stationen.
