Long-duration M2.7 solar flare launches Earth-directed CME, impact expected late on September 1

"The event began at 19:11 UTC, peaked at 20:02 UTC, and ended at 20:41 UTC. The eruption originated from Active Region 4199 (Beta), located near the center of the solar disk.
An asymmetric full halo CME was first observed in LASCO C3 imagery at approximately 20:30 UTC on August 30. Impact analysis suggest Earth-arrival after 20:00 UTC on September 1." W
