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).

Watch the Video down below!

Three new sunspot regions were numbered overnight. Region 1680 is a DAO Beta at 40 millionths in size. Region 1681 is a single spot HSX Alpha type group at 30 millionths in size. Most of  interesting should be new  region 1682 which is a DRO Beta Gamma type region at 30 millionths in size. This region showed moderate growth during the last 24 hours.

Normally, B class solar flares are not that worth for any discussions here, but yesterday, a long duration B8 class solar flare took place peaking at 11:50 UTC from old sunspot region 1678. The duration of the solar flare was over nine hours. Associated with this flare was a non-Earth directed CME (coronal mass ejection). This flare would have measured much higher if it had being on the Earth facing side of the Sun.


  1. Yes!

    That is the one : )

    No doubt a Type IV Halo Event.

  2. very happy to see report posting again.
