SOLAR STORM HEATS UP EARTH'S ATMOSPHERE: A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies. [full story] [video]

 

MIDNIGHT ROCKET PLUMES--POSTPONED: Friday morning's launch of five rockets from NASA's Wallops Flight Facility in Virginia has been postponed. New date: On Sunday, March 25th, between midnight and 3 am EDT, NASA plans a rapid-fire launch of five sounding rockets from Wallops. The rockets will deliver a chemical tracer to the upper reaches of Earth's atmosphere, forming milky white plumes that reveal high-speed winds at the edge of space. The display should be visible to the naked eye from coastal areas between South Carolina and New Jersey. [full story] [updates]

 

SPRING GREEN: Northern Lights continue to flicker around the Arctic Circle despite waning solar wind speeds. What's keeping them going? Answer: It's springtime. For reasons that are still not fully understood, equinoxes favor auroras. Nenne Åman photographed this splash of Spring-green over Arjeplog, Northern Sweden on March 22nd:

"The sky went all green for a few minutes," says Åman. "It was very beautiful and a nice goodbye gift for some friends who were visiting us from Italy!"

NOAA forecasters estimate a 15% chance of polar geomagnetic storms on March 23nd. Considering the season, however, a full-fledged storm might not be necessary. Stay tuned for auroras. Aurora alerts: text, phone.

SUNSET SKY SHOW, AGAIN: A month ago, Venus, Jupiter and the crescent Moon aligned beautifully for evening sky watchers around the world. It's about to happen again. On March 24th, 25th and 26th, the trio will appear side by side in the western sky at sunset. Observing tip: Catch them before the sky fades completely black. These bright objects are extra-beautiful when they are framed by twilight blue. Sky maps: March 24, 25, 26.

Looking for something to do while you're waiting for the Moon to arrive? Try juggling:

"Thanks to my girlfriend for helping me me create these planet action shots on March 22nd," says photographer Kiss Csongor of Derecske, Hungary.
