Can I use two <aside> element in one page


I have start exploring HTML5 and CSS3.
I need suggetion for <aside> element.

I have 3 navigation for my page.
For Ex.
<nav>Primary Nav</nav>
For secondary Nav
<aside>For Third Nav </aside>

I feel two <aside> element are not good for use for secondary and Third nav
but not sure.

Please explain if someone has any thoughts about it
