Asking for more for EOY bonus

Is it possible to ask for more for your EOY bonus (I got $500)? I started in August so I know I'm still very new, but I think I've worked pretty hard. I'm a TS and I got my 6-month training done in 4 months, I've already been involved in a few projects, I'm rolling as a lead for a group within my team, I work on average 45-47 hours a week (I have a friend who has worked more hours than me and also received the same), and my quarterly review was good. I know I'm still new but feel a bit under-appreciated.
