Today’s rare occurrence of a total solar eclipse, an event tracked today in a narrow swath across the entire continental United States, is so monumental – and, to most of us at TVWW, so universally cool – that it eclipses all other programming on TV today. At least on Bianculli’s Best Bets, which today provides an all-eclipse addition. Science Channel is the most prominent to go on cable, and will be providing live coverage, from coast to coast, as the celestial event works its way from Madras, OR to the east coast of South Carolina. Live TV coverage begins there at noon, with the first televised images of totality from the continental U.S. scheduled for 1:15 p.m. ET. And be on time, because these things are seldom late.
