If you're looking to get a view of a massive sunspot that has delighted skywatchers, you better hurry - but be careful.

Normally, catching sight of a sunspot on the sun requires a powerful telescope and a whole lot of special equipment and filters, but a new sunspot has grown so big that you can see it without a telescope at all — but you're still going to need eye protection.
