CMEs MISS EARTH: The Solar and Heliospheric Observatory (SOHO) has observed at least three CMEs billowing away from the sun during the last 24 hours. However, none of the clouds are heading for Earth. The source of the explosions appears to be on the far side of the sun. Aurora alerts: text, voice.

AUTUMN LIGHTS: Northern autumn is only two days away--and that means it's aurora season. For reasons researchers don't fully understand, the days around equinoxes are the best times to see Northern Lights. Indeed, the Arctic Circle is glowing. Last night, Ole C. Salomonsen photographed the ongoing display from Tromsø, Norway:

"The sky was full of awesome auroras in magnifcent shapes and colors," says Salomonsen. "I also saw a magnificent blue fireball streaking through the lights above my favorite mountain Otertinden. It was the biggest fireball I have ever caught on camera. What a great photographic moment for me!"

A string of severe storms brought heavy rain and high winds through the Baltimore region and the East Coast on Tuesday, flooding homes and streets, knocking out power to thousands and forcing local school officials to cancel afternoon activities.

Flash flooding was reported in Columbia and a foot of water covered National Pike in Woodlawn. Waterfront homeowners on Millers Island in Baltimore County saw their streets flooded as water poured over concrete bulkheads along the Chesapeake Bay, through their yards and into their basements.

“Cottonwoods, 70 feet and taller, in full leaf, caught the wind and tipped over at the root base,” said Bradley Evans, general manager of Chugach Electric Association. About 40 percent of the Anchorage-based co-op’s 80,000 meters were knocked out of service by a severe windstorm that swept through the area,

CRESCENT MOON: Tonight, the crescent Moon is passing almost directly between Mars and Saturn. A good view of the western horizon is required to see the crossing. If you have one, go outside just after sunnset and take a look. Sky maps: Sept. 18, 19.

 

AUTUMN LIGHTS: Northern autumn is only days away, and that means aurora season is underway. For reasons researchers don't fully understand, equinoxes are the best times to see Northern Lights--especially around the Arctic Circle. Aurora tour guide Chad Blakley photographed this first sign of autumn from Abisko National Park on Sweden on Sept 14th:

"The auroras were in the sky as soon as the sun went down, and they continued to glow well into the morning," says Blakley. "It was another great night in Abisko."

In North Korea, rain drenched parts of the country, including the eastern coastal city of Wonsan, but did not reach the capital, Pyongyang, which was windy Monday but spared the heavy rains that lashed the South Korean capital.

QUIET SUN: Solar activity is low. NOAA forecasters say the chance of an M-class flare today is no more than 10%. An X-flare is even less likely: less than 1%. No flares are in the offing.

 

NOT AURORAS: For the past week, solar wind has been buffeting Earth's magnetic field, turning skies around the Artic Circle beautiful shades of green. But not every green sky is caused by the aurora borealis. On Friday night, for example, pilot Brian Whittaker was flying 34,000 feet over the Atlantic Ocean when he witnessed verdant hues caused by a completely different phenomenon--airglow. Here is the picture he took from the cockpit window:

"A dark and moonless night away from all lights allowed a great view of this textured patch of airglow," says Whittaker. "The illumination was faint, but it could be seen especially in contrast to the dark ocean abyss below!"
