Bulletin

Solar activity has been very low, no C-class flares in past 24 h. NOAA AR 2610 has rotated over the west limb and NOAA AR 2611 has decayed into a plage, the sun is spotless. Solar activity is expected to remain low.

Proton levels are low and there were no Earth directed CMEs in past 24 h.

Solar wind speed is at 460 km/s with interplanetary magnetic field intensity of 12 nT. Geomagnetic conditions have been quiet, but the rise in speed of more than 100 km/s between yesterday and today, together with increased temperatures and magnetic fields, mark the arrival of the compression region ahead of the expected fast speed stream. There are two coronal holes that will affect the Earth (it was one in the previous rotation, but has now divided and shrank), geomagnetic conditions will increase up to up to minor storm conditions (with possible isolated major storm periods) in the next 48 h.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 10 stations.
