What's up in space 

Sunday, Mar. 25, 2012



Meteorite jewelryDon't just watch shooting stars. Wear them! Authentic meteorite jewelry for Valentine's Day is now available in the SpaceWeather Store.
MIDNIGHT ROCKET PLUMES: On 
Tuesday, March 27th, between midnight 
and 3 am EDT, NASA plans a rapid-fire 
launch of five sounding rockets from the 
Wallops Flight Facility in Virginia. 
 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]

SUNSET SKY SHOW, AGAIN: A month 
ago, Venus, Jupiter and the crescent Moon
 aligned beautifully for evening sky 
watchers around the world. Tonight it's
 happening again. On March 25th and 
26th, the trio will appear side by side in 
the western sky at sunset. Marek Nikodem photographed the Moon making a beeline
 for the planets over Szubin, Poland, on 
 March 24th:
Observing tip: Try catching them before 
 the sky fades completely black. Bright 
planets are extra-beautiful when they are
 framed by twilight blue. 
Sky maps: March 25, March 26.

INCREDIBLE SUNSPOT AR1429: Big 
sunspot AR1429, the source of so many
 strong flares and geomagnetic storms 
earlier this month, is still erupting. 
The active region produced a significant
 coronal mass ejection on March 24th at 
00:39 UT: movie. Because of the sunspot's
 location on the farside of the sun, this
 particular CME will not hit Earth. An 
animated forecast track prepared by 
analysts at the Goddard Space Weather 
Lab shows the trajectory of the expanding
 cloud:
The leading edge of the CME is expected
 to arrive at the STEREO-B spacecraft on 
March 25th at 13:08 UT (+/- 7 hours). 
None of the inner planets will be affected.
Since March began, sunspot AR1429 has
 propelled CMEs into every corner of the 
solar system, stirring up stormy space 
weather around every planet and spacecraft. 
If the sunspot remains active for another
 week or so, it will turn back toward Earth
 for a new round of geoeffective eruptions.
 Stay tuned.
