Where was Snape during the third task?

Hi, I've been wondering for a while now about Snape's whereabouts 
during the third task of the Triwizard tournament. He wasn't 
patrolling round the maze. Until HBP I assumed that he indeed *did* go 
to LV's reunion party, but I was clearly wrong. 

Any ideas?

Cheers, 
Lolita.
