Shocking Sunday


DOUBLE MAGNETIC SHOCK SPARKS BRIGHT AURORAS: On Friday, Jan. 19th, aurora tour guide Sara Skinner of Abisko, Sweden, kept an expectant eye on the sky because she knew that a solar wind stream was approaching Earth. “I told our guests that a display might begin soon,” she says. “What we saw, however, was way beyond what I expected! A crazy vibrant aurora boomed into action, turning everything around us green.”

“There are little words to describe what we witnessed for the next two hours,” she says. “It was totally awesome!”

The strange thing about this display was not its beauty–stunning auroras are seen routinely in Abisko–but rather its timing. The solar wind stream hadn’t yet arrived.

Solar wind speeds wouldn’t begin to increase until hours after Skinner witnessed the outburst. What happened?  A magnetometer operated by Rob Stammes at the Polarlightcenter in Norway may provide an answer. “My instruments recorded a double magnetic shockwave,” he says. “With each pulse of magnetism, electric currents flowed through the ground outside our observatory and bright auroras appeared overhead.”

    I wondered what was tugging on the plate in my head. 😉

    Prediction is for rain starting around 4 pm so I should go out stick walking soon. Yawn.

    Over the top of the hill and east out Grimes Way to Terre View Drive then southwards along the trail to the Birch & Barley after 77 minutes. Wind was biting over the exposed portions but not so later down in the valley. Even noticed a counter-rotor just south of Grimes Way.

    Up above the compost grounds there was a sizable flock of smaller birds mobbing a hawk which stayed around for the thermal rather than flapping to fly away. Later he did, departing over the wapiti which were outside the vet school’s tall fence. Don’t see how those could have jumped over…

      Shortest way home, through the gathering twilight and in the very light rain, provided a total of 113 minutes to begin the week. Did a blackened salmon ceasar salad for omega 3 ration.

    I removed the exhaust fan where the water was coming from, so I can right to the inside of the roof and watch for water running down, rain tonight test. Dang coleslaw cabbage mix went bad even with the expiry on the 27th, 😦 must have coleslaw to survive. bummer.

    Since we’re talking about what we did today…I’m in Portland. The Japanese Gardens were exquisite on this soft, gray day, with a slight drizzle. Near perfection. Yoku dekimashita! After, the gardens, an amazing Japanese lunch. Then to round out the theme for the day, we went to an Asian market in Beaverton. Clouds disappeared (well, almost)…and another walk on Portland’s riverfront, pedestrian bridge…and a tram ride.

    No coleslaw, however. I LOVE coleslaw!!!!
