Pls send rainbows đŸ™

Double rainbow! by Tom

Double rainbow! by Tom

Michigan is drowning right now in some of the worst rains on record. Every day for the last two weeks, from Midland to Grand Rapids to Traverse City, my feed has been full of images of people losing everything to flooding. PLEASE send rainbows.

Just so this post isn’t a totally depressing send-off for your weekend, let me call in one of my favorite websites, Atmospheric Optics. Regarding secondary rainbows or “double rainbows” they say that the secondary is nearly always fainter than the primary, with colors reversed and more widely separated:

Light can be reflected more than once inside a raindrop. Rays escaping after two reflections make a secondary bow.

The secondary has a radius of 51Âș and lies some 9Âș outside the primary bow. It is broader, 1.8X the width of the primary, and its colours are reversed so that the reds of the two bows always face one another. The secondary has 43% of the total brightness of the primary but its surface brightness is lower than that because its light is spread over its greater angular extent. The primary and secondary are are concentric, sharing the antisolar point for a center.

Tom took this near Alma back in 2014. See his latest on Flickr & check out more Michigan rainbows on Michigan in Pictures!

Rainbows Needed

My thoughts this morning are with those who have already been devastated by Hurricanes Harvey & Irma and those who are facing this monster storm.

Everything’s coming up rainbows!

Double Rainbow over the Narrows, photo by Elijah Allen

I guess one of the advantages of getting a lot of rain is that you also get a lot of rainbows! My friend Elijah took this on Monday night. The end of the bow is over the thin channel called “the Narrows” that joins North & South Lake Leelanau.

My position is that should take your rainbows as they come – here’s a beauty featuring the Portage Lake Lift Bridge in Houghton taken this Sunday!

At the end of the rainbow

Memorial Day Weekend is a unique holiday. It’s both a celebration of the beginning of the summer, the weekend to throw off the shackles of cold & gray and embrace sun and sand, and also a somber remembrance of those who have given their lives defending our nation. I hope that light and love touch you in both of these pursuits.

22-Degree Radius Halo

Atmospheric Optics is an excellent resource for rainbows and similar phenomena. Their page on 22-degree halos says:

22Âș radius halos are visible all over the world and throughout the year. Look out for them (eye care!) whenever the sky is wisped or hazed with thin cirrus clouds. These clouds are cold and contain ice crystals in even the hottest climes.

The halo is large. Stretch out the fingers of your hand at arms length. The tips of the thumb and little finger then subtend roughly 20°. Place your thumb over the the sun and the halo will be near the little finger tip. The halo is always the same diameter regardless of its position in the sky. Sometimes only parts of the complete circle are visible.

Much smaller coloured rings around the sun or moon are a corona produced by water droplets rather than ice crystals.

And luck that life can hold
And at the end of your rainbows

Be thou the rainbow in the storms of life.
The evening beam that smiles the clouds away,
and tints tomorrow with prophetic ray.

Frankfort Rainbow

The best rainbow I’ve ever seen last night over Frankfort, photo by Noah Sorensen

Atmospheric Optics from the UK is far and away the best website for rainbow science as well as other atmospheric optical phenomena. Regarding primary rainbows as seen in Noah’s photo from Frankfort, they say:

To see a rainbow we need sunshine and falling rain. Rainbows are rarer than might be thought … Halos occur much more frequently.

Early morning and late afternoon are the best times to see them because the sun must not be too high. Rainbows are always opposite the sun and their centres are below the horizon at the the antisolar point. The lower the sun the higher is the bow.

Red is always outermost in the primary bow with orange, yellow, green and blue within. Occasionally, when the raindrops are small, fainter supernumerary arcs of electric greens, pinks and purples lie just inside the main bow.

A rainbow is not just a set of coloured rings. The sky inside is bright because raindrops direct light there too. The primary bow is a shining disk brightening very strongly towards its rim.
