Let it cool down again. Make sure there is no hint of green left anywhere, because in the coming days you'll be looking for new leaks - so clean up after yourself now to make your life easier later. If the clamps are on well the hose ends won't leak at all, and you'll be done worrying about that hose. When you get a chance, go over the entire system and check for green (or white) anywhere suspicious.
Meanwhile, keep a close eye on the temp needle and after a good drive, top off the plastic overflow tank next to the radiator if you need to (as the system stabilizes it may draw some coolant from the overflow; just top it up if you see nothing else wrong).
