Bulletin
There was 1 C-class flare (C1.3) in the past 24 hours originating from AR NOAA 11836. AR NOAA 11835 has grown more complex and could produce an M-class flare. Solar wind speed is around 380 km/s and the interplanetary magnetic field Bz component around 0 nT. Geomagnetic conditions where quiet, but are expected to reach active (K=4) to minor storm (k=5) levels in the evening of August 30th due to the arrival of the fast stream of a coronal hole.
