Bulletin

Solar activity was low over the past period. A C1.4 flare originated from Catania group 26 (newly numbered NOAA 2506) in the eastern hemisphere, peaking at 12:29 UT. Catania group 26 (NOAA 2506) showed signs of further development but its flaring potential remains low. Quiet solar conditions with flaring below C level is expected over the next days. No Earth directed CMEs have been observed in coronagraph data. Solar wind speed continued to decline to values currently under 300 km/s. The total magnetic field was in the 6-8nT range with Bz variable and the phi angle mostly in the negative sector. There are so far no indications of the possible northern polar coronal hole influence on the solar wind. A slight enhancement of the solar wind conditions does however remain possible. Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 1-2). Quiet to unsettled geomagnetic conditions can be expected.

Today's estimated international sunspot number (ISN): 026, based on 12 stations.
