Spritely Sunday

1a

“AURORA SPRITES” OVER NEW ZEALAND: Last night in Otago, New Zealand, Ian Griffin counted more than a dozen “aurora sprites” dancing over Hoopers Inlet. “The display was very beautiful,” says Griffin, “with ghostly auroral sprites putting on a display that lasted for several hours.”

Also known as “picket fence auroras,” these vertical rays trace lines of magnetic force connecting Earth to space. The luminous columns show where beams of energetic particles are being guided toward Earth’s upper atmosphere by magnetic fields.

    Pay no attention to the Russians and rich boy, focus on Obomber wiretapping rich boy instead. *snicker*

    Snowing here this AM, enough to require I sweep off the satellite dish again, ugh.
    Thunderstorms expected later in this latest bout with Gulf of Alaska Low pressure systems.

    Snow teased us here earlier this morning but, thank goodness, it stopped!

    I’ve been meaning to post about this for a few days…today seems like a good day, it being Den’s typical Sunday science focus.

    It says more than I care to know about our “culture” that when a so-called entertainer dies, it’s plastered all over social media, etc. but when a renowned scientist dies (perhaps more so when it’s a woman), there’s not much notice. Mildred Dresselhaus should be a household name to inspire future science and math students — whatever their gender.

    TVD bridge and return in a dawdling 52 minutes. A flock of 14 little birds, black with white underwings, perched in the tall, old evergreen. The same loud but invisible birds both coming and going.

      Then to the Hillside Cafe for supper. When I was just finishing Emmy came over and asked to join me; of course! Emmy is an honors college freshman and this semester an RA over in Global Scholars Hall, the newest dorm and over in the Northside area. But Emmy doesn’t like the food there so comes to the Hillside Cafe for her dinner, same as last semester when she lived in Honors Hall, where her boyfriend from high school still resides. She is majoring in chemical engineering and he is majoring in computer science.

      I encouraged attending School of Music events and in the course of showing her some of the listings for this semester learned that she played flute for 4 years. So I suggested she might want to play in the concert band next fall semester. As we are likely to talk again, I’ll probably have a chance to encourage it further.
