Solar activity was very low with no significant flaring and X-ray flux at background values. NOAA region 2638 (Catania 95 and 96) and NOAA region 2639 (Catania 97) were stable. Additional spot formation was recorded in Catania group 98 (now numbered as NOAA region 2640). X-ray flux is expected to remain at background level. No Earth directed CMEs have been recorded in coronagraph data. The transequatorial extension of the negative polarity southern polar coronal hole has transited the central meridian overnight. It is expected to become geoeffective around midnight February 28 / March 1. Proton flux values are at background levels and expected to remain so.

Solar wind showed the continued recovery towards nominal conditions. Solar wind speed declined from around 500 km/s to around 430 km/s. Total magnetic field was in the 3-5nT range. Solar wind is expected to be at nominal levels over the next 48 hours before an anticipated increase late February 28 due to high speed stream from the negative polarity coronal hole. Geomagnetic conditions have been quiet to unsettled (local K Dourbes 0-3, NOAA Kp 1-2). Over the next days, geomagnetic conditions are expected to be quiet to unsettled and increasing to quiet to active by late February 28 with the anticipated high speed stream.
