There hasn't been any news of Apple streaming it, so you can't watch it live.
I was wondering the same thing, because the event will start at 5 PM and I won't be able to watch it until 8 PM. But if I try to search the keynote video, I will see a thousands of spoilers. So it's quite impossible, until someone posts a link before the keynote, where the video should be.
www.apple.com will have it

Here's a countdown timer.

You could visit www.macrumors.com and check the top of the page for the countdown. Then add that time to your current time.
I know where the timer is, but if I went to Apple's website, I'd instantly see a big iPhone 5 screen. :/
/e Oh, thanks for the Apple events link![]()
No live feed because the news isn't that big this year. Also why the venue is small: A small venue for a small 4S.
