Bulletin

New active region NOAA AR 2480 produced a C1.0 flare peaking at 06:17 UT. More C-class flares can be expected. A halo CME occurred yesterday at 14:12 (LASCO-C2). This event is backsided and not expected to arrive to the Earth. A previous slow CME (12:00 UT, 250 km/s) was in the field of view of LASCO-C2 when the second one started, CACTus merged these two events and emitted an alert as a full halo CME. The second CME had an angular width of 100 degrees, originated from a filament eruption close to the eastern limb and was mostly directed to the south-east, but a glancing blow at the Earth cannot be discarded late on January 10. due to the slow speed of this CME not more than active conditions should be expected. The Earth is still under the influence of a fast solar wind stream, with speeds around 570 km/s and interplanetary magnetic field magnitude of 5 nT. Unsettled to active conditions have been recorded, the situation is expected to remain unchanged for the next 24 h.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 057, sur la base de 02 stations.
