The full effect of Monday’s total eclipse could only be experienced in what’s known as the path of totality — a 115-mile-wide band that ran northeast from Mexico’s Pacific coast through cloudy southwest Texas, past the heart of Indiana, over Major League Baseball fans gathered hours early in Cleveland, past Niagara Falls and through Maine into Canada. But only where the weather cooperated.
About 44 million people live within the track, and a couple hundred million more reside within 200 miles.
“This may be the most viewed astronomical event in history,” said National Air and Space Museum curator Teasel Muir-Harmony, standing outside the museum in Washington, awaiting a partial eclipse.
In the Bay Area, total solar eclipses — where day turns to night, stars come out, temperatures drop and birds stop singing — are extremely rare. The last one visible over San Francisco occurred 600 years ago, on June 26, 1424, according to NASA.
And the next one won’t happen until 228 years from now, on Dec. 31, 2252.
The next total solar eclipse that will be visible anywhere in California will occur on Aug. 12, 2045, according to NASA, following a path that includes far Northern California communities like Redding, before it moves across the nation to Florida. -Paul Rogers
