Bulletin

Solar activity has been eruptive during the past 24 hours, featuring two low C flares from NOAA 11778 and NOAA 11781. More C flares are possible within the next 48 hours, with a slight chance for an M flare, especially from NOAA AR 11778, 11780 and 11781. Solar wind density increased around 5:00 UT on June 29, while wind speed and temperature began to rise, marking the arrival of the expected coronal hole high speed stream. Meanwhile, solar wind speed has increased from about 360 km/s to 500 km/s. In the past 24 hours, geomagnetic activity has been at quiet to active levels (K Dourbes between 1 and 4; NOAA Kp between 2 and 4). A rise to minor storm levels is possible on June 30 and the first half of July 1st, due to an expected glancing blow from the CME of 02:00 UT on June 28. Quiet to active levels are likely in the second half of July 1st, and a return to quiet levels is expected on July 2nd.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 050, basierend auf 14 Stationen.
