Egad! My response last week to Fred Carcress of Catonsville, who asked about the next lunar eclipse, was wrong by 12 hours. Yank that one off the fridge and tear it up. Here's the real deal, I promise: The next total eclipse of the moon visible from Maryland begins at 4:50 A.M. on Aug. 28. The full moon will move deep into the Earth's shadow, but the show ends in mid-eclipse when the MOON sets here at 5:34 a.m. Thanks to all who set me straight.
