During last 24 hours solar flaring activity has somewhat increased and seven B-class flares were reported. The flaring activity mostly originated from the NOAA AR 2770 (not numbered by Catania) that is presently observed on the East solar limb. We can expect B-class flares and possibly also isolated C-class flares in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

Earth is presently inside the fast solar wind (speed of about 600 km/s), associated with the low latitude extension of the northern polar coronal hole which reached central meridian on July 30. During last 24 hours the interplanetary magnetic field magnitude was fluctuating between 6 and 12 nT, and its present value is 5 nT. The equatorial coronal hole of positive polarity has reached central meridian this morning, the associated fast solar wind can be expected at Earth on August 06. The geomagnetic conditions were mostly unsettled with one interval of active conditions reported early this morning (Dourbes reported K=4 and NOAA reported Kp=4). Presently geomagnetic conditions are unsettled and we can expect such a conditions to persist in the coming hours. Since the solar wind speed is still rather high, together with the longer intervals of negative value of the Bz component of interplanetary magnetic field, it can induce the unsettled to possibly active geomagnetic conditions in the coming hours.
