How often do political campaigns have to report financial information to the FEC?

I am trying to follow the US Senate race in my state and when I go to the FEC's website the last information was filed on December 31, 2009. Do campaigns have to report that information only at the end of the year or is it every 6 months or 4 months? Is there any other ways to find out how much a candidate's campaign has raised aside from the FEC website?|||Quarterly during the year. More frequently 30 days, as the election approaches.





You can find out more info on the election committee website for your state.|||Once a month, do a yahoo search and you will find out more or call your local political party and ask
