Two different Domain Authorities for one site?

[reddogmusic]

The "Domain Authority" of my site on the "Link Analysis" section of SEOmoz Pro (34) is different to what it is on Open Site Explorer (36) - how can this be? All I can think is that one hasn't been updated yet (I'm hoping the lower one!).

Elucidation gratefully received!

I'd also say that's the most logical explanation. On your 'Campaign Overview' page you can check 'Last Linkscape index update' to see if this differs from the date displayed in Open Site Explorer.
