Filament Eruption, Earth-Directed CME

 Late on July 28th, a filament in the sun's northeastern quadrant erupted. It sent an asymmetric halo coronal mass ejection into space.

While the eruption is quite earth-directed, it is also fairly weak. The forecast is for impact to occur early on August 1st, with Kp 4 conditions likely, and a chance for G1 (Kp 5) or even G2 (Kp 6) storms. High and even mid-latitude sky watchers should stay alert. 

Also of note, an M4.1 solar flare occurred on the sun's west limb on July 28th at around 1600 UTC. It launched an impressive CME into space; however, due to its location, the eruption was not earth-directed. 

The flare triggered an S2 (moderate) solar radiation storm. HF radio operators in the polar regions may have noticed some loss of signal. An S1 (minor) storm is still in progress, it should subside in the next day or so.
