text:  Now tonight, another comet named for German astronomer Heinrich Olbers will be visible. Olbers is listed as a Halley-like comet, though its orbit is slightly faster and therefore makes more frequent appearances, as in once every 69 years, as opposed to nearly 80 for Halley's comet. Olbers will most likely be appearing within the constellation Lynx. Eben Brown, Fox News. Fox's Jeff Manasso reports teachers in Chicago could soon be walking a picket line.
