Solar activity was low. The strongest event was a C3.3 flare from Catania group 27 (NOAA 2506) peaking at 5:55UT. Catania group showed flux emergence and growth of its trailing spot. Other regions were stable or in decay. Flaring is expected to be below C level although another isolated C flare from Catania group 27 remains possible. An equatorial coronal hole connected to the northern polar coronal hole has past the central meridian around midnight and may be influencing the solar wind at Earth location around March 1. SDO/AIA 193 shows a mass ejection originating from near S15E75 around 4:00UT. A clear off-limb dimming is visible. Awaiting confirmation from coronagraph data the event is preliminarily assessed to have limited angular extent and will hence most probably not be geoeffective. Coronagraph data are required to confirm this. Solar wind slightly decayed from around 430 km/s to around 390 km/s while total magnetic field was in the 4-7.5 nT range. Bz was variable though not below -4nT and mostly positive. The magnetic field phi angle remained in the positive sector. Solar wind conditions are expected to remain in this slightly enhanced state. Geomagnetic conditions were quiet (NOAA Kp 0-2) and are expected to remain so.
