Bulletin

Only 4 C-class events were observed over the last 24 hours. The strongest reached a maximum of C2.6 at 03:59UT (3 July) and originated from a region just behind the Sun's east limb. It was associated to a fast, not Earth-directed CME (about 1400 km/s). Of the 9 visible sunspot groups, NOAA 2104 remains the largest and most complex region, still having a magnetic delta. However, it did not produce a C-class flare. NOAA 2100, 2106 and 2107 produced each a C1-flare. The long filaments resp. near NOAA 2106, about 20 degrees west of NOAA 2107, and in the southwest quadrant, are still present but -for the moment- stable. C-class flares are expected, with a chance on an isolated M-class flare. A solar wind structure arrived at ACE near 23:30UT. Wind speed jumped from about 320 to 350 km/s. Bz turned southward around 02:30UT and remained between -4 and -8 nT for nearly 9 hours before returning to positive values. The impact on the geomagnetic field was minimal, as only quiet geomagnetic conditions have been recorded so far (K < 4). A small equatorial coronal hole that passed the central meridian on 30 June may affect Earth on 4 July. Quiet geomagnetic conditions are expected, with locally a brief active episode possible.
