Solar flaring activity over the past 24 hours was at low levels with three C-class flares. A C4.2-class flare, peak time 15:33 UTC, and a C1.7-class flare, peak time 17:20 UTC, were produced by a region behind the west limb on Aug 02nd. Currently there are two active regions on the visible solar disc. NOAA AR 3068 (beta-gamma) underwent further growth and development, and produced a C1.3-class flare, peak time 02:24 UTC on Aug 3rd. NOAA AR 3070 has decayed into plage. The region in the north-eastern quadrant, now numbered as NOAA AR 3071 (alpha), remains simple and inactive. The flaring activity over the next 24 hours is expected to be at very low to low levels with probable isolated C-class flaring.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been below the1000 pfu threshold and is expected to remain below the threshold in the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) remained under the mild influence of a high speed stream (HSS). The solar wind velocity varied between 480 km/s and 560 km/s. The interplanetary magnetic field was weak to moderate with a maximum value of 8.2 nT and a weak Bz component reaching -5.6 nT. The B field remained in the negative sector (directed towards the Sun). The solar wind parameters are expected to remain slightly enhanced over the next 24 hours under the influence of the HSS.

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Quiet to unsettled geomagnetic conditions are expected over the next 24 hours with possible isolated active periods.
