The newly available coronagraph data show two halo CMEs, and one partial halo CME. All three CMEs seemed to have source regions at the back side of the Sun as seen from Earth, and they are therefore not expected to arrive to Earth.
The first halo CME was faint and slow and was first observed in the SOHO/LASCO C2 field of view at about 13:25 UT on September 07, the second halo CME was much brighter and it was first observed in the SOHO/LASCO C2 field at 11:36 UT on September 08. From the shape of the CMEs it looks like they originated from the same, behind the West solar limb active region. The bright partial halo CME with the angular width of about 130 degrees was first observed (above the East solar limb) in the SOHO/LASCO C2 field of view at about 02:24 UT on September 08.
