Solar Eclipse. On Monday, Jan. 26th, the Moon will pass in front of the sun producing an annular “ring of fire” eclipse. This is not a total eclipse; the Moon will cover only 93% of the sun’s surface. Nevertheless, the Moon’s dead-center transit across the solar disk will produce a sight of rare beauty for observers along the “path of annularity.” Best views are to be had from islands in Indonesia where the ring of fire will appear to sink into the ocean at sunset. Meanwhile, in Australia, southeast Asia, southern parts of India and South Africa, observers will experience an off-center partial eclipse. Crescent-shaped sunbeams will dapple the ground while high overhead the Moon takes a curved bite out of the sun. Visit for eclipse maps, timetables and photos. [] 01 24 09

Approaching Comet. Comet Lulin (C/2007 N3), discovered in 2007 by a collaborative team of Taiwanese and Chinese astronomers, is swinging around the sun and approaching Earth. The photogenic comet has a bright tail and an “anti-tail” visible in mid-sized backyard telescopes. At closest approach in February, Comet Lulin is expected to brighten to naked-eye visibility. Visit spaceweather.comfor sky maps, pictures and more information. [] 01 11 09

Solar Cycle Update. Final sunspot counts for the year 2008 are now available and the numbers are very low. The sun was utterly blank–that is, it had no sunspots whatsoever–on 266 days last year. That makes 2008 a century-class year in terms of low sunspot numbers. To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days. Now for the good news: Evidence is mounting that the deep solar minimum of 2008 is coming to an end; we can expect a livelier sun in 2009. [] 01 04 09

First Meteors of 2009. The annual Quadrantid meteor shower peaks on Jan. 3rd when Earth enters a stream of debris from shattered comet 2003 EH1. The timing of the encounter favors observers in western North America and across the Pacific Ocean who could see dozens to hundreds of meteors during the dark hours before sunrise this Saturday morning. Visit for a sky map and more information. [] 01 03 09

Movie Night POSTPONED The movie night event originally scheduled for Saturday, January 10th will be postponed a week until the 17th due to a forecasted winter storm. 01 09 09
