Solar activity was very low. Just a single B2.5 flare was reported from region NOAA 2582. This region newly emerged just South-East of former region 2597. Some new flux emergence and spot formation was also recorded in NOAA 2580 by the end of the period while NOAA 2581 showed consolidation of its leading spot. X-ray flux is expected to remain below C level with a chance for an isolated C flare. Proton flux levels are at background values and expected to remain so. No Earth directed CMEs have been observed in coronagraph data.

Nominal solar wind conditions were observed with solar wind speed slowly decreasing to around 400 km/s. Total magnetic field was at or below 5nT with a variable Bz component. The magnetic field phi angle indicated a negative sector throughout the period. Solar wind conditions are expected to see later today or early tomorrow a sector boundary crossing into a positive sector (away from the Sun) followed by the onset of a high speed stream from the transequatorial coronal hole.

Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Geomagnetic conditions will become enhanced over the next 24 hours as a consequence of the sector boundary crossing and the coronal hole high speed stream. First up to active and later up to minor storm levels must be expected.
