Bulletin

NOAA 2381 has simplified considerably, with the other seven sunspot regions relatively small and quiet. Four C1 flares were recorded: three produced by NOAA 2381, and one by an active region at the southeast limb. A small filament eruption was observed near disk center around 08:00UT. Based on currently available imagery, no Earth-directed coronal mass ejections (CME) have been observed.

C-class flares are expected, with still a small chance on an isolated M-class flare.

Solar wind speed declined further and is now between 350 and 400 km/s. Bz varied between -3 and +3 nT. A sector boundary crossing is anticipated for 08-09 July. A positive equatorial coronal hole has passed the central meridian and may affect the earth environment starting 10 July.

Quiet to unsettled geomagnetic conditions are expected, with a small chance on an active episode.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 121, gebaseerd op 10 stations.
