Hi Conor,
It is interesting to see these kinds of Sunspot groups developing so far away from Solar Maximum! Thanks for the link.

To me astronomy is looking up and thinking "What the heck is going on up there!!"

Well were over the min now and starting to climb up the sunspot scale again, as we seen a few backwords sunspots. This AR is now starting to decline in size but more action is on the way!

[font=arial][size=2]An explosion on the sun yesterday produced a burst of 18-22 MHz radio waves so intense "it sounded like a freight train rolling through," says astronomer [/size][/font][email=ashcraft@heliotown.com][u][font=arial][color=#0000ff][size=2]Thomas Ashcraft[/size][/color][/font][/u][/email][font=arial][size=2]. He recorded the sounds using his shortwave radio telescope in New Mexico: [/size][/font][url=http://www.heliotown.com/Radio_Sun_Introduction.html][u][font=arial][color=#0000ff][size=2]listen[/size][/color][/font][/u][/url][font=arial][size=2].[/size][/font]

For days it has been erupting and throwing clouds of magnetized gas high above the sun's surface where we can see them. Soon, we'll see the sunspot itself. The sun's rotation is turning the spot toward Earth and it could emerge later today.
