Blood Moon is sometimes used to describe a Total Lunar Eclipse. When the Earth casts its shadow on a Full Moon and eclipses it, the Moon may get a red glow. Total lunar eclipses are rare – only about one in three lunar eclipses are total. About four to five total eclipses can be seen at any place on Earth in a decade. Every once in a while, four total lunar eclipses happen in a row. This is called a lunar tetrad. The total lunar eclipses happen 6 months apart. There are at least six full Moons between two total lunar eclipses in a tetrad. The last of the current tetrad was September 28th, and the next one will not occur till 2033. There were a lot of watchers out along with photographers to document the event. I did not get out until late, as the moon was not visible here locally until later. The shot below was taken from the popular Clover Island looking due East. This is where I have taken many photos of the bridge and the lighthouse. If you missed it, you will have a long wait for the next one.
