What is this noise?

Hi all,

How would you fix or diagnose this noise?

It goes on in my apt at about 5am every morning when everyone is getting up to use the showers...

Do you have a steam heating system?

I'm not sure. I just moved in and I know nothing about plumbing .. I will try to find out and get back to you.
