Space Weather Update: M4.7 solar flare, G1 storm

We have had a quiet summer when it comes to space weather but our Sun is starting to kick into a higher gear right as autumn approaches for us on the northern hemisphere.

Sunspot region 2860 developed rapidly during the past 24 hours and is now a complex sunspot region with a Beta-Gamma-Delta magnetic layout. This resulted in a long duration M4.79 solar flare (M1-minor) which peaked at 06:11 UTC. Type II and IV radio emissions were associated with the solar flare and this suggested the event was eruptive. Due to the location of sunspot region 2860, it is very likely that the resulting coronal mass ejection has an earth-directed component.

But that’s where the good news ends. When up to date coronagraph imagery became available from STEREO and SOHO it became quickly obvious that the resulting coronal mass ejection should be called nothing less than a disappointment. A slow and very faint coronal mass ejection became available with a mostly southward trajectory. While it could give us a glancing blow in 4 to 5 days from now, we expect nothing from it. The C3.0 solar flare CME is a much more interesting event and that coronal mass ejection could arrive on Monday.
