AR1515 CME MYSTERY-Why are all of these large CMEs from 1515 directed so far to the south? This region has been well-positioned to slam the Earth with hot plasma but for some unknown reason the blasts are being deflected well south of the ecliptic plane. I don't really have a theory for this puzzling enigma, however I have noticed something unusual.

If you look at the far left of the STEREO Ahead EUV images, there's a pyramidal formation parked directly over the equator between 1515 and 1513.

I don't know if this is some kind of magnetic field or a DARPA deflector shield experiment; but it does seem to be deflecting the coronal mass ejections away from the equatorial/ecliptic region. If this "cap" breaks down or dissipates we may see more Earth-directed CMEs. Does anyone have a theory about this "structure"? I've never seen anything like it.
