22 degrees at Van’s Beach, photo by Andrew McFarlane
Atmospheric Optics is an excellent resource for rainbows and similar phenomena. Their page on 22-degree halos says:
22º 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.
Lots more at Atmospheric Optics!

Suttons Bay … vernal equinox sunrise panorama, photo by Ken Scott Photography
Monday’s Michigan in Pictures is coming to you a little early so you have a chance to be aware of the vernal equinox tomorrow morning (Monday, March 20, 2017) at 6:29 AM EST. EarthSky editor Deborah Byrd’s article on the vernal equinox has a ton of great information, video, and illustrations and explains:
…there’s nothing official about it, it’s traditional to say the upcoming March or vernal equinox signals the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. This equinox does provide a hallmark for the sun’s motion in our sky, marking that special moment when the sun crosses the celestial equator going from south to north … At the equinox, Earth’s two hemispheres are receiving the sun’s rays equally. Night and day are approximately equal in length. The word equinox comes from the Latin aequus (equal) and nox (night).
Read on for more including how you can mark due east and west from any location on the equinox!

May you have all the happiness
And luck that life can hold
And at the end of your rainbows
May you find a pot of gold.

September 13 – Stars and Cars Part 4, photo by Andrew Pastoor
I was on the fence about posting this, but after I found this cool photo I just had to! Michigan Radio reports that a new law directing the Michigan Department of Transportation to increase speed limits to 75 miles an hour on up to 600 miles of rural highways in the state will have consequences:
Russ Rader of the Insurance Institute for Highway Safety says there’s decades of research proving that more people will die as a result. For every five miles’ increase in the speed limit on interstates and highways, says Rader, fatal crashes increase 8%.
He says Michigan is not alone; many other states are also raising speed limits. He says very high speeds cancel out the life-saving features on cars like seat belts and front air bags.
“In 2013 alone, speed limit increases resulted in about 1900 additional deaths,” says Rader. “That would essentially cancel out the number of lives saved that year from front air bags.”
Read on for more and get more about the law from mLive, It will go into effect following studies.
