A weak slow partial halo coronal mass ejection (CME) was detected in LASCO/C2 data to
lifting off the solar surface around 04:00 UTC on Sept 16. The CME has an estimated
projected velocity of around 300 km/s. The CME is related to a prominence eruption
from behind the south-east limb and has no Earth-directed component. No impacts are
expected on Earth.
