1ST COMET FLYBY: No kidding. Green comet 41P/Tuttle-Giacobini-Kresak is
flying over Earth's North Pole this week where sky watchers can find it
all night long not far from the bowl of the Big Dipper. At closest
approach on April 1st it will be just 21 million km from Earth--an easy
target for backyard telescopes and almost visible to the naked eye.
