G1 klasse zonnestorm verwacht op 4 en 7 oktober
Oorzaak zijn 2 coronale gaten die nu aardegericht zijn.
Two holes in the sun's atmosphere are turning to face Earth, each spewing a stream of solar wind toward our planet. Estimated times of arrival: Oct. 4th and Oct 7th. NASA's Solar Dynamics Observatory took this false-color UV picture of the gaseous firehoses on Oct. 1st:
NASA: SDO
These are "coronal holes"--places in the sun's atmosphere where magnetic fields open up and allow solar wind to escape. They are dark because the glowing-hot plasma normally contained there is missing, now en route to Earth.
Solar wind spewing from the smaller hole (right) will arrive first, causing polar geomagnetic unrest but probably not a full-fledged geomagnetic storm. Solar wind escaping from the second, larger hole (left) will follow days later bringing a chance of G1-class storms. In both cases, equinox cracks in Earth's magnetic field will permit the solar wind to spark Arctic auroras

4th of October. The Northern Lights did a several hour slow dance routine for us tonight, and a few twists along the way to spice things up. #aurora #northernlights #tromsø https://t.co/AvKVyzUI21 pic.twitter.com/4ShF6BkLBd
