Sunny Sunday

RETURN OF THE BIG CORONAL HOLE: At the end of October, a hole in the sun’s atmosphere lashed Earth’s magnetic field with solar wind, sparking moderately-strong geomagnetic storms and almost a full week of Arctic auroras. News flash: It’s back. The same “coronal hole” is turning toward Earth again. NASA’s Solar Dynamics Observatory photographed the structure on Nov. 19th:

Coronal holes are regions in the sun’s atmosphere where the magnetic field peels back and allows solar wind to escape. Since our last encounter with this hole in late October it has been transiting the farside of the sun, carried around by the sun’s 27-day rotation. Now that it is back we can see that the hole is not quite as large as it was a month ago–but it is still impressive, covering almost 1/3rd of the visible solar disk.

NOAA forecasters expect the leading edge of the emerging solar wind stream to reach Earth on Nov. 22nd, bringing with it a chance of G1-class geomagnetic storms.

    More Auroras on tap for the upper latitudes, I used to see them all the time in N MN,

    Brady, the last of the original Mimn, came out just as I was finishing raking the leaves in front into the street for the city to pick up in the next few days. Brady, finally, has a lady friend! Very good looking, too.

    Who said this!

    “Darkness is good…Dick Cheney. Darth Vader. Satan. That’s power. It only helps us when they (liberals)…get it wrong. When they’re blind to who we are and what we’re doing.”

    Lotsa petitions to sign.

    So just as I began stick walking to the Birch & Barley it began to rain and kept it up, not hard, for the entire 108 minutes. Went via the top of Terre View Drive around clockwise. Saw two robins in a tree by the Valley Road Playfields and then a kestrel on the telephone wire just over the pass along Terre View Drive.

    Anyway, my knees are damp and the outer pockets of my 1970s rain forest parka no longer are completely waterproof. No damage done.

    Trumpland really was on Showtime! Then why couldn’t we find it listed? Maybe they only ran it the once?

    I agree with Den about how many dumbasses there are now, closing in on half of us. It WAS more like 1/3. I attribute it to the right-wing poison machine, working constantly since Reagan to dumb people down, to brainwash their thinking so they would vote for their enemy. Toss in our education system, but that was them, too, working to stop people from learning. They also put a lot of energy and work into preventing people from voting.

    When I opened the living room curtains this morning I had a terrible shock. My crabapple tree right by the front deck had fallen over. The trunk was split, toppling the tree. 😦 My baby, I planted that as a mere whip 37 years ago. The side of it towards the back of the house was dying, no leaves the last couple years, so I guess the front half had the most weight and we had high winds all day and night, and all day today.

    Jill’s Brian came over with his chainsaw and cut it up a bit, dragged the piece away from the house and now I’ll have to figure out how to get all that wood to the backyard bonfire pit. I think Brian said he would come back and help me. I wish it weren’t so cold out today. If it was warm like a couple days ago I could work on it tomorrow.

    But SHIT! I lost my flowering crab and I’m broken-hearted. It had white flowers, so beautiful in spring. When I ordered the whip in 1979 I ordered a pink one. I was stuck with white all these years, but she was still pretty as all crabs are.

    Cold and windy now but I’m going out for a bit anyway. I try to go out every evening year round.
