Bulletin

Solar activity was restricted to a few B-class flares, contributed by NOAA active regions 2561, 2563 and 2564 (Catania numbers 3, 4 and 6 respectively). No Earth-directed CMEs were observed. Flare activity at the C-level is possible (40% chance).

The solar wind disturbance remains due to high speed stream influences. The solar wind speed obtained values up to 650 km/s. The magnetic field magnitude ranges between 5 and 10 nT, with a fluctuating Bz. The disturbance caused geomagnetic activity up to K=4 (local at Dourbes) levels and up to K=5 for a few time slots (global Kp of Potzdam and NOAA). Geomagnetic conditions are expected to return to quiet to unsettled levels during the next 24 to 48 hours. Another enhancement of the solar wind speed may follow from July 11 due to influences of a following coronal hole, which caused solar wind speeds of more than 700 km/s during the past Carrington rotation.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 059, basierend auf 22 Stationen.
