Halo Sunday

AFRICAN ICE HALO: You never know what you might see when you go on safari. “Earlier this week I was riding through Choose National Park in Botswana,” says George Kourounis. “While the rest of the people in the vehicle were scanning the bushes, looking for lions and leopards, I was looking up in the sky at this complex solar halo.”

“It was almost like a giant eye in the sky looking down at us,” says Kourounis. “I’ve never seen anything like it.”

Halos like this are caused ice crystals in high cirrus clouds. Shaped like pencils, long and thin with 6 sides, the crystals bend and refract sunlight into a variety of shapes. Shown above is a 22-degree circular halo, a circumscribed halo, and a fraction of a full parhelic circle.

Some people think ice halos are rare in Africa–but they are not. The air 10 km high is freezing over Africa just like everywhere else. Safari-goers should definitely look up, from time to time.

    While Earthlings are on the planet trying to destroy each other, amazing things are happening above. Beauty needs to be elevated up beyond hate, peace will never happen otherwise.

    Gardening While Black — TNYT today.

    Well, well, TNYT adopts the Strunk “‘s” for the possessive for even words ending in “s”.

    Easier for computer algorithms anyway.

    I just learned that Stanford Cardinal is the colour, not sure bird. Use a tree as a mascot.

    I suppose better than an original plan to call the team “Robber Barons”.

    Dodgers fail to win the World Series, Drat!
    I was really pulling for those guys being fellow West Coasters,
    just wasn’t meant to be, there’s always next year, it never ends.

    Kirk took the Dodgers loss hard:

    Cooked today, that was it in the line of work around here. Tried to catch up w/ some of the things I have recorded on the DVR, and of course, used my computers.

    Hair cut tomorrow, that’s about it at this end.
