Sunspots and aurora
Last weekend's polar lights have been witnessed by millions around the world. While many drove to dark places to watch this celestial spectacle, others grabbed a lawn chair and watched the baffling show from their own backyard. Children were woken up by their parents to watch the colours in the sky. The 10-11 May aurora certainly captured the attention and awe of the public and the media.
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)***
X-class festival continues!
The high solar flare activity continues as NOAA 3664 has produced the strongest solar flare (X8.7) so far this solar cycle. ***UPDATED (10)***
The show continues!...
NOAA 3663 produced its 4th and -so far- strongest X-class flare on 6 May.
X-class flares!
Active region NOAA 3663 produced an X1.6 flare early on 3 May. Further M-class flaring can be expected from this sunspot group, with a chance on another X-class flare. ***UPDATED (2)***
