Two partial halo CMEs were observed in coronagraphic imagery. The first CME (first measurement in SOHO/LASCO C2 at 16:36 UT on July 9) was associated with a filament eruption occurring near S00E15 and is propagating east from the Sun-Earth line with a projected plane of the sky speed of 520 km/s (CACTus estimation).
The second CME (first measurement in SOHO/LASCO C2 at 7:12 UT on July 10) was associated with a prominence eruption occurring near Catania region 3 (NOAA AR 2104) and is propagating west from the Sun-Earth line with a projected plane of the sky speed of 760 km/s (CACTus estimation). For the first CME, the arrival of a glancing blow from the CME-driven shock wave is expected on July 13 near 0 UT. The second CME has less chances to arrive at Earth, but minor signatures of arrival might still be possible on the UT morning of July 13.
