Solar activity was very low. The largest flare of the period were a B9.7 flare from around the East limb peaking at 01:09UT and a B5. The most prominent region NOAA AR 2505 showed signs of decay. Solar activity is expected to be quiet with a possibility for an isolated C flare. No Earth directed CMEs were recorded in coronagaph data. Earth was in slow solar wind conditions with velocity in the 340-390 km/s range and total magnetic field dropping back to nominal levels of 3-5 nT. The magnetic field Bz was variable and the phi angle mainly in the negative sector. Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp between 0 and 2). Nominal solar wind conditions with associated quiet geomagnetic conditions are expected to continue. The possible influence of a weak high speed stream from the extensions of the Northern polar coronal hole may, from tomorrow onwards, slightly increase solar wind conditions leading to quiet to unsettled geomagnetic conditions.
