1Mercury Transit: Monday brings a daytime attraction for astronomy fans when Mercury, right, passes across the face of the sun. It's a fairly uncommon sight, with the last one happening 10 years ago and the next one visible in the United States in 2019. If nothing else, to see a tiny planet silhouetted like a tiny, intense sunspot gives a striking view of the size of the sun. But this is not something you can just go outside and look at. You need a solar telescope to protect your eyes. The St. Petersburg College Planetarium is setting up telescopes 9 a.m.-2:30 p.m. Monday to safely watch with special filters. The observatory is best accessed from 69th Street at Fifth Avenue N. Free. St. Petersburg College, 6605 Fifth Ave. N, St. Petersburg. (727) 341-4320.
