Catania sunspot group 70 (NOAA AR 1660) still has the potential to produce a C-class flare. A B5.4 flare peaking around 03:31 UT in this group was accompanied by coronal dimmings and a post-eruption arcade, but with only a weak and narrow CME (according to STEREO COR2 data) that is not expected to arrive at the Earth. The Earth is currently inside a slow (around 290 km/s) solar wind flow with weak (around 1-2 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions in the coming hours. On January 25 we expect the arrival of a fast solar wind stream emanating from a low-latitude coronal hole in the southern hemisphere, possibly resulting in active geomagnetic conditions.
Today's estimated international sunspot number (ISN): 042, based on 09 stations.
