SOLAR WIND SPARKS AURORAS: For the third day in a row, a high-speed stream of solar wind is blowing around Earth. First contact on Aug. 4th rattled our planet’s magnetic field and produced a brief but intense display of auroras over Canada. Catalin Tapardel witnessed the outburst from Kakwa, Alberta:
“I looked out the window at 4:30 am and was amazed by the Lady Aurora dancing above, high up in the sky, fighting the dawn,” says Tapardel. “I stormed the door, picked my camera up, in the process I forgot to grab the tripod, and everything was recorded hand-held.” He posted a 4k video of the display at the Alberta Aurora Chasers Facebook page.
Since then, the stream’s steady pressure has done little to upset the equilibrium of our planet’s magnetic field. No strong geomagnetic storms have been observed. NOAA forecasters say there is a 45% chance of minor geomagnetic storms on Aug. 6th.
