The Great Cosmic Coincidence of Feb. 24, 2009

Source - Space Weather News for Feb. 23, 2009: http://spaceweather.com

COSMIC COINCIDENCE: What are the odds? On Tuesday, Feb. 24th, Saturn and Comet Lulin will converge in the constellation Leo only 2 degrees apart. At the same time, Comet Lulin will be making its closest approach to Earth--the comet at its best!-- while four of Saturn's moons transit the disk of the ringed planet in view of backyard telescopes. Oh, and the Moon will be New, providing dark skies for anyone who wishes to see the show.

The best time to look is around 1 a.m. Tuesday morning (your local time) when the planet-comet combo ascend high in the southern sky. To the unaided eye, Comet Lulin looks like a faint patch of gas floating next to golden Saturn. Point your backyard telescope at that patch and you will see a lovely green comet with a double tail.

Visit http://spaceweather.com for full coverage including photos, sky maps, and a live webcast.

Geographic Notes: Comet Lulin is visible from all parts of the globe--all longitudes and both hemispheres. Directions are reversed in the southern hemisphere; there the comet is located in the northern sky around 1 am. Saturn is globally visible, too, but the special quadruple transit of Saturn's moons starting around 3 a.m. PST on Feb. 24th is visible only to observers around the Pacific Rim.

Comet Lulin Update

Source - Space Weather News for Feb. 18, 2009: http://spaceweather.com

COMET LULIN UPDATE: Comet Lulin is approaching Earth and brightening rapidly. Observers say it is now visible to the naked eye as a faint (magnitude +5.6) gassy patch in the constellation Virgo before dawn. Even city dwellers have seen it. Backyard telescopes reveal a vivid green comet in obvious motion. Just yesterday, amateur astronomers watched as a solar wind gust tore away part of the comet's tail, the second time this month such a thing has happened. Lulin's closest approach to Earth (38 million miles) is on Feb. 24th; at that time the comet could be two or three times brighter than it is now.

SATELLITE DEBRIS: More than a week has passed since the Feb. 10th collision of Iridium 33 and Kosmos 2251 over northern Siberia, and the orbits of some of the largest fragments have now been measured by US Strategic Command. Today's edition of http://Spaceweather.com features global maps showing where the debris is located. Only 26 fragments are currently plotted, but that number will grow as radar tracking of the debris continues. Check back often for updates.
