Bulletin

Solar activity has been very low, no C-class flares. Active region NOAA AR has developed its magnetic field configuration into beta-gamma, C-class (and low chances of M-class) flares can be expected. No Earth directed CMEs were detected. The Earth is under the influence of a high speed stream from a coronal hole. As a consequence, in the past 24 h minor storm conditions were reached at Dourbes (K = 5, at 23:00 UT on September 2) and major storm conditions at planetary levels (Kp = 6 at 06:00 UT today). Currently, solar wind speed is at 680 km/s with magnetic field intensity of 6 nT with negative (oscillating) Bz. Increased geomagnetic activity is expected to persist for the next 24 h.

Today's estimated international sunspot number (ISN): 066, based on 20 stations.
