The reported partial halo CME as observed on 30 July at 13:36UT by SOHO and reported by CACTUS, is actually a combination of at least 2 separate CMEs on different locations on the Sun, hence creating the illusion of a wide angle CME. SOHO, SDO and STEREO imagery indicate that the first CME seen in
LASCO-imagery at 13:36UT originates from an eruption in old active region NOAA 2113 on the backside of the Sun. This region was responsible for several M-class flares during its previous transit, and will round the east limb within the next two days. The associated CME was slow (about 300 km/s
plane-of-the-sky speed) and is directed away from Earth.  The second CME originated from a filament eruption on the visible disk south of NOAA 2131 around 18:00UT, shortly after a data gap in SOHO-imagery. This was a narrow, but fast (800 km/s) CME directed to the southeast. Also this CME has no Earth-directed component.
