    Is there anyway to observe this without becoming blind?

    Sure. Use a telescope with a hydrogen-alpha filter if you have cash, or a metal-film filter if you don't.

    Go the SOHO webpage. Or get a solar filter for your telescope.

    No danger to your eyes, but perhaps danger to your telescope or more likely, the eyepiece.

    Indeed. If you value your optical equipment, never expose it to direct sunlight. Instead, use an aperture filter.
