The first truly visible lunar eclipse in three years will happen in the early hours of Tuesday morning.The eclipse should begin at 3:51 a.m., as this chart (which is not adjusted for daylight savings time) will show. The eclipse will reach its peak at 5:37.With moon slated to set at 5:53, there won’t be a whole lot of time to see it, but anyone who’s willing to get up early should still get a pretty good view. Or lack of view, so to speak.Bruce Twarog, a professor of astronomy in Kansas University’s department of physics and astronomy, said that the best bet for viewing the lunar eclipse is to use your naked eye.”The field of view is so large,” he said, “that it would be even more difficult to look at it with a telescope.”
