Mercury and the Moon Make Rare Moves: this week on the Storyteller's Night Sky

May 13, 2019

The Full Moon on Saturday, May 18, is a rare Blue Moon (the third Full Moon in a season with four Full Moons). It occurs at 5:12 pm edt, and will rise at 9 pm, just as the Sun is setting. It won't look blue.

At the middle of this week, Mercury comes to what I’ll call its “Full” phase, and at the end of the week, the Moon achieves its rare Blue Moon phase. We won’t see Mercury, and the Moon won’t appear blue, but still they’re both good for story!

So here’s the thing with Mercury: Later this year, in November, Mercury will make a rare transit in front of the Sun. This only happens about 13 times a century, so it’s kind of a big deal. This week, on Thursday, Mercury will be exactly opposite the place where it will transit, so this is why I said it’s at its Full phase, because it’s standing opposite. This is the peak in Mercury’s cycle as messenger, so pay attention to all communications!

Then on Saturday, the Moon will come to its Full phase for the third time this season, and because there will be four Full Moons this Spring, this Saturday’s Full Moon is what’s traditionally known the Blue Moon. For the Moon to achieve fullness four times before the season expires is much more rare than to have two Full Moons in one calendar month, so on top of the Mercury position, this Blue Moon adds an extra-special layer of celestial wonder.

So what should we do? Maybe write a love letter and mail it to yourself, or to the secret beloved, but don’t open it until the Mercury transit in November. Include your best wish for what is to come, and then let it go. It’s really a terrific experience to set an intention, offer it up to the postal service, so it can be carried it into the world, and then let it come back. Lots of things can happen along the way!

Emily Dickinson said it this way:

This is my love letter to the worldThat never wrote to me,--The simple news that Nature told,With tender majesty.Her message is committedTo hands I cannot see;For love of her, sweet countrymen,Judge tenderly of me!
