There are two numbered sunspot group presently visible on the solar disc, Catania sunspot group 77 and 78 (NOAA ARs 2625 and 2626), and both of them have alpha configuration of the photospheric magnetic field. Accordingly, solar activity is low, with no C-class and only one B-class flares reported during last 24 hours. We expect solar activity to remain on the same low level. The faint and slow partial halo CME was first seen in the SOHO LASCO C2 field of view at about 21:30 UT (straight after the data gap) on January 16. The bulk of the CME mass was directed northward from the Sun-Earth line, and this stealth-like CME with presently unclear solar counterpart, will most probably not arrive to the Earth. More will be reported when additional data become available.
The Earth is still inside the slow solar wind with the speed, similar as reported yesterday, of about 320 km/s. The interplanetary magnetic field magnitude is about 6 nT. The fast solar wind, associated with the elongated equatorial coronal hole extended towards the south, which has crossed central meridian yesterday, might arrive at the Earth late on January 18 or in the morning of January 19. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours. The expected arrival of the fast solar wind might induced disturbed geomagnetic conditions (we expect up to K=4).
Today's estimated international sunspot number (ISN): 031, based on 17 stations.
