Solar Sling Sunday

GOODBYE SUNSPOT AR2736: Active sunspot AR2736, which hurled a CME toward Earth on March 20th, is about to leave the face of the sun. NASA’s Solar Dynamics Observatory took this extreme ultraviolet picture of the sunspot’s seething magnetic canopy tipping over the sun’s western limb on March 23th:

By Monday or Tuesday, AR2736 will vanish as it begins a 2-week trip around the farside of the sun.

Meanwhile, the sunspot still poses a threat to Earth even though it is no longer directly facing our planet. In fact, in a way, the sunspot poses a greater threat while it is near the edge of the sun. As the sun rotates, the sun’s magnetic field spirals out into the solar system like water flowing from a lawn sprinkler:

Because of the sweep of this spiral, Earth is well connected, magnetically speaking, to the edge of the sun. If AR2736 flares while it is there, the ejecta could be funneled back to Earth, potentially causing a solar radiaton storm.

    I can recall the time when groceries were placed into the “used” cardboard boxes by the “box boy” in which the store received the goods from their suppliers.

    My grandma, in a small town in Wisconsin, owned and operated a “corner store” where her customers usually came in with their own carry-home bags.

    Nodded to a new neighbor from California, walking her big dog, out from the house across the street. Then the standard 14 minutes to the north door of the Hillside Cafe.

    So synopsis of Muller report, Trump says he’s exonerated. Well, then, might as well release the entire report for us to see.

    As for being exonerated, what about all the indictments of people working for Trump, talking to Russians. What’s all that about if not about Trump?

    Sick of it all, he just better not win again in 2020. Nothing else is going to get him out of there.

    Wouldn’t that be a trumpet?
