Thanks sunfighter. I googled it but couldn't find a definitive answer, but I did see an example of code that used it twice, so I thought it was okay.
The way I understand it the contents within the <aside> could be removed without reducing the meaning of the page or the <article>
That's my understanding of what differentiates an article from a section. Articles can basically be removed and stand on their own (like a blog post) whereas sections basically, but not exclusively, replace divs. Anyway, I used the <aside> tags exactly as my example above.
