Bulletin

Solar activity was at very low levels. On disk signatures of an eruption were observed at around 18:30 UT on Jan 19 from a newly emerged region in the north east of the solar disk, as yet unnumbered by NOAA. The observed region produced a small flare and coronal dimming indicating the existence of a possible associated Coronal Mass Ejection (CME). However, no coronagraph images are currently available to confirm the existence or direction of the CME. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at very low levels.

The solar wind speed fluctuated between from 280 km/s to 350 km/s (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector). Bz varied between -3 and +3 nT.

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 0 and 1. Quiet to unsettled conditions are expected on Jan 20-22 with possible isolated active conditions on Jan 20, due to the combined influence from the patchy negative polarity coronal hole that traversed the central meridian on Jan 16 and the CME that was observed on Jan 14.
