Space Weather Impacts On Climate

OFF-TARGET CME MIGHT GRAZE EARTH: We wouldn’t call it a full-fledged eruption. On Sept. 11th, a magnetic filament in the sun’s southern hemisphere fluttered–just enough to hurl a faint CME into space. The bulk of the CME will miss Earth, sailing south of our planet, but there is a chance of a glancing blow on Sept. 14th. Any impact would increase the disturbance already expected on Sept. 14th due to the coronal hole, described below. CME impact alerts: SMS Text.

BUTTERFLY-SHAPED HOLE IN THE SUN’S ATMOSPHERE: A hole has opened in the sun’s atmosphere, and it is venting a stream of solar wind toward Earth. NASA’s Solar Dynamics Observatory photographed the 500,000-km-wide butterfly-shaped gap on Sept. 11th:

POLAR VORTEX

THE POLAR VORTEX WOBBLED IN DECEMBER: Last month, sky watchers in Europe saw something rare and beautiful. A giant bank of polar stratospheric clouds (PSCs) escaped the Arctic Circle, and for more than a week they filled skies with rainbow color as far south as Italy. In the Italian comune of Sanfrè (latitude +45N), Pablo Javier Lucero was able to photograph the clouds at all hours of the day:

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
