Coronal hole, weak shock passage, filaments
Periods of minor G1 geomagnetic storming conditions were expected this weekend because a northward extension of the southern polar coronal hole was facing Earth. Enhanced solar wind flowing from this coronal hole was expected to influence Earth the past few days but it is clear now that this anticipated solar wind stream never arrived at Earth. Geomagnetic conditions have thus been relatively calm this weekend, far away from any kind of geomagnetic storm. This changed however this morning as a weak shock passage arrived at Earth.
