In the hours before the December solstice, the full Moon will pass through the Earth’s shadow for a total lunar eclipse that will be visible at some point from all of North America. Depending on your longitude and time zone, this event will be visible anywhere from the evening of the 20th through the morning of the 21st. There are several stages during an eclipse, which are marked by the time the leading or trailing edge of the Moon makes contact with the Earth’s shadow. This month’s column provides information about the total lunar eclipse and other celestial events during the month of December.
