Bülletään

Solar activity was very low during the period, with no C-class flares or higher reported. The currently visible sunspot regions are decaying. NOAA 2628 has a stable leading spot but a decaying middle portion. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Mostly quiet flaring conditions are expected, with a small chance on an isolated C-class event.

Solar wind speed declined from about 510 to 440 km/s, with Bz mostly fluctuating between -2 nT and +3 nT. The interplanetary magnetic field was directed away from the Sun. A small positive equatorial coronal hole (CH) started its transit of the central meridian.

The geomagnetic field was at unsettled to quiet levels and is expected to remain so. Starting 27 or 28 January, the arrival of the CH's particle stream may affect the earth environment.
