Bulletin
The solar activity has been at very low levels over the past 24 hours. The unipolar sunspot group (NOAA 2755) is slowly decaying and did not produce any significant flaring activity. The X-ray flux is below B-level. The solar activity is expected to remain at low levels for the next 24 hours.
No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.
The expected enhancements in the solar environment due to the influence of the negative polarity and patchy coronal hole (which faced Earth around Dec 29-30) has arrived yesterday on Jan 5 around 17:00 UTC. The total magnetic field reached 14.6 nT, the solar wind speed increased up to 575 km/s, and the southern component of the magnetic filed fluctuated between -14.4 nT and 11.1 nT, as recorded by the ACE spacecraft. Then the total magnetic field decreased to remain below 5 nT, and the solar wind speed is currently fluctuating between 450 km/s and 545 km/s. The enhanced solar wind conditions are expected to persist as long as the Earth remains under the influence of the solar wind coming from the patchy coronal hole. A long North/South extended equatorial coronal hole was facing Earth in the past 2 days. Enhancements in the solar environment due to the associated speed streams are expected to come on January 8.
Active geomagnetic conditions were observed with Kp-index (NOAA) and K-Dourbes equal 4 on Jan 5 at 18:00 UTC in response to the solar wind enhancement. Quiet to unsettle conditions is expected for the next 24 hours.
