Earth-facing CME looms as Sun sparks auroras and Comet McNaught brightens the sky

SpaceWeather.com reports an Earth-directed CME from two solar filament eruptions with an ETA around Aug 11–12, potentially triggering auroras near the Perseid meteor shower, while a moderate G2 geomagnetic storm is already in progress as Earth sits in the CME wake. Separately, Comet 220P/McNaught underwent dramatic outbursts, brightening to binocular visibility with observers noting a shock-wave-like debris shell; the page also features aurora imagery and various sky-watching updates.
