Minor Geomagnetic Storm

The solar wind continues to increase this morning and is now over 500 km/s. The Bz component of the Interplanetary Magnetic Field (IMF) was tipped sharply south for several hours and a G1 Geomagnetic Storm is currently underway. We expect aurora at very high latitudes!

New region 1683 numbered

All three sunspot regions remain visible. The largest region 1682 decreased in size during the last 24 hours. It is now a DAI Beta-gamma type group at 110 millionths in size. New sunspot region 1683 was numbered overnight, it is a HSX Alpha type group at 90 millionths in size. There is now more than one spot visible and a bipolar magnetic configuration.
No C class solar flares took place yesterday, the largest solar flare was a B8 from region 1682. Only C class solar flares are expected today.

Spectacular Prominence Eruption

Early this morning, a prominence located off the southwest limb erupted.

The Sun spewed out a blob of plasma.


Here you get a close up 











As a result of this we notice a outstanding CME on Soho imagery (Soho Lasco C2 here).

Due to the location of this event (southwest limb),
most of the plasma cloud looks to be heading away from Earth.

Full Halo Coronal Mass Ejection (CME)

The STEREO Ahead Spacecraft captured a Full halo Coronal Mass Ejection (CME) this morning. 

The source of this event was a filament eruption inbounded with a solar flare near old region 1678 off the farside of the Sun. 


The Coronal Mass Ejection (CME) will not be geoeffective (farsided event).
