J ohn Guthmann, in Cockeysville, noticed that the summer solstice this year fell on June 20. "This is the first time I have seen the summer solstice fall on the 20th of June ," he says. No wonder. It's a rarity. The last time was in 1896. But you may catch the next one, in 2012. This one barely made it -- 11:59 p.m. on June 20 (Universal Time). Most fall on the 21st, but the 22nd, too, is possible. Don't wait up. The next is in 2203.
