This description is almost poetic:
The cause of this magnetic tranquility was identified as a gentle gust of solar wind […] essentially resembling flutters traveling down the sides of Earth’s magnetosphere, excited by the Sun’s breath. This is akin to the effect of blowing across a piece of paper and making it flutter.
Following are two excerpts from the article:
“On October 17, Rob Stammes, a Norwegian citizen scientist, detected a rare magnetic oscillation in Earth’s magnetic field from his space weather observatory in Lofoten, Norway. The event, termed a “pulsation continuous” or Pc3 in this case, lasted for over 20 minutes and was caused by a gentle gust of solar wind. The event was unexpected as it occurred near the Solar Maximum, contrasting with the typical appearance of Pc3 waves during low geomagnetic activity in the Solar Minimum.”
“Although Pc3 waves can sometimes flow around Earth’s magnetic field and result in a “tearing instability,” leading to magnetic reconnection and subsequent geomagnetic storms, this did not occur on October 17. The magnetosphere returned to its state of tranquility following the oscillation.”
