Where's the NASA TV channel?

As the title says - I need to find it but don't see it in the listings. I wish to record the historic lunar event coming up in the weeeeee hours of Friday morning local time (3:30AM or similar)

I am sure I've seen NASA TV on U-verse before, but now can't find it.

264.
