There are currently 9 sunspot groups visible. Fast growing NOAA 2132 produced the strongest event of the period: a C8 flare peaking at 00:18UT. Together with NOAA 2130, which produced only low-level C-class flares, they are magnetically the most complex active regions on the solar disk. NOAA 2127 simplified, and remained quiet. A small filament on the northern hemisphere near the central meridian (CM) erupted. Evaluation of any associated CME is pending the availability of coronagraphic images. The other filaments have been stable. No Earth-directed CMEs were observed over the last 24 hours. There remains a chance for an M-class flare, in particular from NOAA 2130 and 2132. In response to the sector boundary crossing from 31 July around 11:00UT (ACE), solar wind speed gradually increased from 300 to 350 km/s, with Bz varying between -8 and +10 nT. Geomagnetic conditions were quiet, with locally some unsettled periods towards the end of the reporting window. A small equatorial coronal hole is transiting the CM and may influence the geomagnetic field on 4 August. Quiet geomagnetic conditions are expected until the possible glancing blow from the 30 July CME, which may locally lead to active geomagnetic conditions on 2 August.
