Bulletin

The solar activity has been quiet over the past 24 hours. The X-ray flux remained below B-level, and the visible solar disc is spotless. Solar activity is expected to remain at low levels.

Some few narrow and slow solar Coronal Mass Ejections have been observed at the limb but no Earth directed component has been identified. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind parameters continued to slowly return toward nominal values. The wind speed decreased from about 400 to 340 km/s. Total interplanetary magnetic field strength was below 5.5 nT. The southward magnetic component remained between -4.5 and 3.0 nT. The solar wind speed is expected to decrease further and remain at ambient background and slow solar wind speed regime for the next 24-hour period. A small equatorial coronal hole of negative polarity is now facing Earth, this might influence and slightly enhanced the solar wind parameters on January 13.

The geomagnetic conditions were quiet and are expected to remain quiet during the following next 24-hour period.
