WEAK IMPACT: A coronal mass ejection hit Earth's magnetic field around 0852 UT on July 11th, but the impact did not provoke strong geomagnetic activity. Nevertheless, high-latitude sky watchers should remain alert for auroras as a fast stream of solar wind blows around our planet.

EASTERN UNREST: An active region emerging over the sun's eastern limb is hurling material high above the stellar surface. This eastern unrest is not Earth directed. Forecasters say the greater threat for geoeffective activity comes from sunspot 1247 (finder); it has a "beta-gamma" magnetic field that harbors energy for M-class solar flares. There is a 10% chance of such eruptions during the next 24 hours.
