Huge coronal hole faces Earth – G2 geomagnetic storms forecast for May 19 2017

Strange Sounds – May 18, 2017

Check out this huge coronal hole on the sun as it could be a chance to reach geomagnetic storm levels on May 19-20 2017.

Indeed, during the last rotation, this coronal hole caused solar wind speeds up to 750km/s and a lot of geomagnetic storming.

The NOAA SWPC has a moderate G2 geomagnetic storm watch in effect for tomorrow evening (UTC) which could very well be possible considering the history of this coronal hole.

Well worth to keep your eyes on the solar wind data starting tomorrow evening to see how this is going to develop.

Especially for our southern hemisphere sky watchers this could be a very interesting events as their nights are becoming longer and longer.
