If you missed the International Space Station when it passed over Baltimore Sunday evening, you may get a second chance tonight, if skies remain clear as the giant tinker toy passes just north and west of the city.

Actually, some observers did manage a glimpse of the station Sunday. There was a layer of thin clouds over the region, and no stars were visible. But Venus could just barely be seen through the haze. And if you can see Venus in the southwest after sunset, you will likely be able to see the ISS. They're just about the same brightness these days. And sure enough, we did spot the station as it passed just right of Venus and crossed the sky from southwest to northeast.

Tonight's flyby will follow a very similar track, offset just a bit to the north and west. 

Look for a bright, steady, star-like light to rise over the west southwest horizon at 5:40 p.m. It will pass well to the right of brilliant Venus and reach its maximum elevation - about two-thirds of the way up the northwestern sky - at 5:42 p.m.  Then it will pass by the W-shaped constellation Cassiopeia and zip off toward the northeast, disappearing at 5:46 p.m.
