sunspot? or no sunspot?

Hi
Can someone please tell me what is the best way to find out if there are sunspots or not on a given day?
How long will a sunspot be visiable for?

Hi,

Try this website. It's a nasa page.

Or better still, click the picture of the Sun on the left hand column of every IceInSpace page.

The MDI image shows the visible surface features pretty well.
A sunspot can be visible for a few hours throught to a couple of weeks, sometimes even more with very large groups. They change their structure very quickly so every day is different!

I really like Spaceweather.com (http://www.spaceweather.com) You'll get current sunspots and also flares from there, as well as lots of other interesting stuff! Highly recommended. :thumbsup: Although no much is happening at the moment.
