Bulletin

Solar activity is very low, no C-class flares in past 24h. There are active regions (NOAA AR 2880, 2481, 2482) capable of producing some in the coming hours. Solar wind speed at the Earth is 450 km/s with interplanetary magnetic field magnitudes of 5 nT. Geomagnetic conditions have been quiet and are expected to remain so, except if the CME from January 6 arrives to the Earth late on January 10 (20% chances) and elevate conditions to active levels.

Today's estimated international sunspot number (ISN): 089, based on 05 stations.
