Be real careful about viewing the sun or any planets that are transiting across its face. You can find articles on safe viewing of the sun over at
Sky & Telescope or
Astronomy Magazine, or you can use Google to find some other publication that knows what it's talking about; i.e., an astronomy magazine and NOT, e.g., the NY Times. Don't take any one person's advice, including mine. Rather do a little research and find out for yourself (your eyes are on the line)!
Here's one such article. Note: so-called "sun filters" sold with cheapo telescopes are generally not sufficient.

Good article. But I don't think I want to wager my eyesight on a $3 pair of eclipse shades.

The absolute safest way to observe the sun, is through a pin hole in a blocking sheet (whatever you have), properly focused, and allowed to hit a white panel beneath it. The image is displayed with detail, and allows you to watch it continuously, with no fear of harm to your eyes!
We went to White Lake, NC, in 1973(?) for a solar eclipse, and we set up a couple of these things. They work.
Idiot me, decided that I could look at the thing directly, when it was in full coverage. I have a little round dead spot in my vision as a result. Oops!
I did a google search of pinlole viewers... this is one of the responses:

The safest way to view this transit is still the time-tested method of screen projection where the image of the sun through a pinhole onto a sheet of white paper.
Slightly more elaborate is to use a telescope or binoculars to project an image. Benefit is more light. Disadvantage is possible heat buildup in the optics and danger of someone thinking they can look through the telescope safely in this mode. Also you have more trouble tracking the sun unless you have a motor drive mount.
Next come filter materials over naked eye. Disadvantage is that the image is very small and you are assuming that someone made the filter correctly. Hard to know for sure unless it is verified by the manufacturer. I really see no advantage with this for a simple transit event because of the small image size.
Next comes filtering over the telescope objective. Advantage is a large image with detail. Disadvantage is that you have to be absolutely certain that the filter is correct for your application and does not leak light or could come off accidentally at any time. It must go over the objective and never over the eyepiece.
Finally, all eyepiece sun filters sold to amateurs are very dangerous to use because they can easily break due to heat. The only safe eyepiece filters are the costly professional types of filters (e.g., h-alpha).
You can enjoy this event safely and I would suggest a projection method to do so.

Looks like this will be mainly viewable in Europe. Bummer...

So starting on June 8, the "VIRGO'S" rule the Zodiac!
We have waited since 1882 for this!

Another alternative is the
SunSpotter.
Pros: Highly rated sun scope. You get a nice big projected image of the sun. So it's fairly safe.
Cons: Costs $335. Not idiot proof. Not child-proof. You'd have to supervise closely any idiots or children who happened to be using it.

This won't work for this, but you can see the shape of the sun during a partial eclipse by looking at light filtering through trees.
The spaces in the leaves act like lenses. When the sun is a crescent, you see small crescents all over the pavement instead of circles!
I saw this during the last partial eclipse in CA.

We use the pin-hole viewers as well. My kids are looking forward to this, they LOVE astronomy and star-gazing!
