Flare productivity from NOAA 13664 and the extreme geomagnetic storm on 10-11 May rank amongst the most impressive in the space weather domain. A perspective.

The King is dead, long live the King?

While NOAA 3664 has rounded the Sun's west limb, a new X-class flare producing active region has shown up near the Sun's east limb.

Sunspots and aurora

While many witnessed last weekend's polar lights, the aurora do not always require very high sunspot numbers.

Extremely severe geomagnetic storm!

As expected, the first in a series of CMEs has arrived and unleashed its full power, resulting in an extremely severe geomagnetic storm. Further severe storming this weekend is possible. ***UPDATED (4)***
