G2 geomagnetic storm, M2.9 solar flare
Thursday, 27 August 2015 09:03 UTC
Geomagnetic conditions have been at the moderate G2 geomagnetic storming level in response to an extended period where the direction of the IMF (Bz) stayed southward. Source of this activity is unknown but we think this might be one of the faint and slow M-class coronal mass ejections that passed our planet, which would explain the lack of any solar wind speed or density increase.
Fantastic aurora displays have been reported from many locations around the world. Below you will find a quick selection of fantastic images made by photographers around the world during the past 24 hours:

M2.9 solar flare
Sunspot region 2403 remaines in a state of decay but it did found the strength this morning to produce an M2.9 (R1-minor) solar flare that peaked at 05:44 UTC. There was no coronal mass ejection associated with this event. More M-class events are becoming more unlikely as the magnetic complexity of sunspot region 2403 diminishes.
