COMMENT: Solar activity is extremely quiet. Yesterday (27/02), the
western part of the large filament erupted. Evidence of the eruption is
seen in EIT 195 at 10:00 and in EIT 304 at 13:19 UT. The associated CME
is first seen in LASCO c2 at 10:34 UT. Due to its westward position, we
do not expect major geomagnetic consequences. No proton event was
recorded. Later at 21:30 UT another CME was seen in c2 at the East limb,
it is determined backsided. The solar wind speed is still elevated at
600 km/s, the IMF is mostly pointing North. This results in quiet (Kp=3)
geomagnetic conditions. The high wind speed is attributed to the coronal
hole, now situated near the West limb. We expect its influence to
diminish soon.
