Betelgeuse Sunday

One day, perhaps in our lifetimes, perhaps a million years from now, the red giant Betelgeuse will dim a little–and then explode. The resulting supernova will rival the full Moon and cast shadows after dark, completely transforming the night skies of Earth. No wonder astronomers are closely tracking the current “fainting of Betelgeuse.”

“Fainting” is an actual astronomical term. It means dimming, the opposite of brightening. And right now, Betelgeuse is definitely fainting.

Edward Guinan of Villanova University and colleagues caused a minor sensation last month when they reported “[Betelgeuse] has been declining in brightness since October 2019, now reaching a modern all-time low of V = +1.12 mag on 07 December 2019 UT. Currently this is the faintest the star has been during our 25+ years of continuous monitoring.”

    Whenever I read CAROL’S description of her computer hiccups, I think to myself, “thank goodness those hiccups haven’t happened to my computer” … because I wouldn’t have a clue what to do about it! *knock wood*

    But, weatherwise..in the past 10 days, 100 inches of snow have fallen on Mt. Baker.

    It’s expected we’ll get some snow later today in the lowlands. …and it’s gonna be COLD… Bitter cold air from B.C.’s Fraser Valley is expected to settle over Western Washington for several days, with daytime temperatures around 20 degrees on Monday and Tuesday and a low of 6 degrees Monday night.

    The big, scary ice storm didn’t amount to much here at the ranch. Can still see the grass thru the crunchy snow. Hopefully, it will melt tomorrow. I did go over the deck and sidewalk, but it was glued to the boards and sidewalk. Getting one layer of the crunch off will assist in the melting when it comes.

    My computer is still fine, no freezing up AT all. IT’S CURED!!!
