The E-mail Commentary from Eco-Justice Ministries
The Super Blue Blood Moon
In today's Eco-Justice Notes, I almost take a break from matters of great significance. An astronomical event of passing interest leads me into considerations of categorical confusion and media hype. Ultimately, though, my light-hearted musings of the day do lead to some practical comments on how we can easily be distracted from matters of great significance.
Doesn't that sound better than yet another analysis of the State of the Union speech?

The excited news release from Cape Canaveral, Fla, said:
On Wednesday, much of the world will get to see not only a blue moon and a super moon but also a total lunar eclipse, all rolled into one. There hasn't been a triple lineup like this since 1982, and the next won't occur until 2037.
Wow! A triple lineup of lunar events! Let's look at each part.
Add all of these up and we get the headline-worthy name of a "Super Blue Blood Moon."
The wonderful children's TV show, Sesame Street, had a recurring exercise in observation and critical thinking tied to a little song.
One of these things is not like the others,
Out of the triple lineup of lunar events, which one is not like the others? Which one just doesn't belong? (I'll wait while you decide ... Time's up!)
Both the super moon and the eclipse have to do with details of the actual orbital path of the moon. An outside observer could notice and describe both events accurately. A blue moon, though, has nothing to do with our satellite's orbit; it only has to do with how the very regular appearances of a full moon line up with the quirkily irregular Gregorian calendar ("30 days hath September ..."). Somebody using a different calendar would never notice a blue moon.
That opening news release has things garbled. It gushed that we can see "not only a blue moon and a super moon but also a total lunar eclipse, all rolled into one." For most of us, a total lunar eclipse is the dramatic sight worth some special effort to see. (Here in Colorado, this week's was an early morning event, with totality beginning at sunrise.)
A super moon is an interesting curiosity, giving us the opportunity to say, "Golly! Look at the size of that moon!" when we see it rising. Or, if you live in a low-lying section of Miami, "Golly! My street is flooding again!"
There is absolutely nothing to see about a blue moon that looks any different from any other full moon. It is just a full moon at the very end of a calendar month. The announcement that you can see a blue moon by looking at the sky instead of your calendar gives the notion that the moon is doing something unusual. That mistaken impression can be displaced by looking at the beautiful regularity of a graphical lunar calendar, which shows the phase of the moon for each day. The patterns of nature are far more dramatic than the oddities of our calendars.
The strange excitement about this week's eclipse mixed together two different categories of events -- astronomical and calendars -- and tried to tell us that the celestial events were more important because of a calendar detail. (Watch out for December 31, 2028, when there will be even more hype about the New Year's Eve Blue Blood Moon!)

Jumbling categories is fun for those who are looking for unique and distinctive experiences. It allows a fairly routine event to be seen as remarkable. (While there's another total lunar eclipse in less than a year -- Jan. 21, 2019 -- the next super blue blood moon isn't until 2037!) But mixing up dramatically different types of events or experiences or analysis can be dangerously confusing and distracting.
In these Notes, I often talk about things that are "in the headlines." But those headlines are as likely to be about celebrity gossip as they are about significant events. Most of us have well-honed filters to distinguish between important news and journalistic fluff, but more and more, the way stories are presented on-line can make it both harder and more important to be attentive to the difference in the categories. Watch out for "click bait" that tries to deceive you. And watch out for presidential tweets (perhaps a better phrasing is "tweets from the president") that push trivial matters up to the top of the news feed, and displace more consequential topics. "In the headlines" is a broader category than "makes a difference."
The two different categories of lunar events, I said, are defined by whether an outside observer could describe them. The moon's perigee and an eclipse are universally recognizable. A blue moon depends on our calendar's frame of reference.
That "outside observer" test is a good one to remember. Are issues that are important to you related to events in the world that would be noticed by somebody outside of your circle of friends, or your political bubble? Would the outside observer show you things that you're not noticing?
The outside observer test helps avoid two problems.
A little bit of media coverage of this week's Super Blue Blood Moon isn't that big a deal. My overblown reaction to those stories, though, has led me to take a closer look at the confusion and distortions that we often encounter in categorizing and experiencing more important things.
Let's remember that outside observer, and check in frequently to see if our categories and perceptions are legitimate.
