Bulletin

No C-class (or higher) flares were observed over the last 24 hours, while the x-ray background flux remained close to the C1-level. There are currently 9 sunspot groups visible on the solar disk, with NOAA 2104 and 2107 being the largest and both having a magnetic delta. NOAA 2106 quieted down after its M1-flare from yesterday noon, part of the filament still being present. The CME associated to this flare was mainly directed to the north. It will deliver at most a glancing blow late on 5 July, with little influence on the geomagnetic field expected. Active regions are just behind the east limb, and 2 long filaments are present on the solar disk (one in the southwest quadrant, another about 20 degrees west of NOAA 2107). C-class flares are expected, with a chance on an isolated M-class flare. Solar wind speed decreased from 350 to 300 km/s, while Bz varied between -2 and +2 nT. Geomagnetic conditions were quiet and expected to remain so.

Today's estimated international sunspot number (ISN): 111, based on 21 stations.
