The Super Blue Blood Moon

It’s all about the name, what’s with that?

“Super” comes from the proximity of the Moon to Earth. The Moon this time around is about as close as it can be to Earth when it is full. I believe the previous full moon was about 1,000 km closer than this one.

“Blue” comes from the second definition of a Blue moon and any place I look this up the definitions seem to be in the same order. I like to call them Type 1 and Type 2:

1. The third Full Moon in an astronomical season with four Full Moons (versus the usual three).
2. The second Full Moon in a month with two Full Moons.

We will get another “Type 2” blue moon in 2018 occurring in March. The next “Type 1” blue moon happens next year in May.

and finally

“Blood” is for the color sometimes seen in an eclipsed moon.

We have all three of these things happening on Wednesday 31 January, and this is a combination we seldom get to see so have a look if you can.

Oh but can you? Below is a cartoon of when and where the viewing will be. For me, the setting moon is the time. Will I see it? Ha, my forecast is for clear and cold Wednesday morning, low temp will be somewhere around -11 C, so I would assume it will be perfect and near the horizon I might get some good color.
