You saw an occultation.  In a true *grazing* occultation, the star disappears 
and reappears more than one time, typically over a period of less than a 
minute.  Since the star you were observing disappeared for only five minutes, 
you would have been able to see a graze not very far south of your location.

Back in SAC's salad days, trips were organized in which large groups of us 
would set up at regularly spaced stations along a graze path, and do timings 
that could be used to refine the profile of the moon's limb.
