Detecting when a peripheral stops advertising

Is it possible to tell when a peripheral has stopped advertising? When I'm showing my BLE connection UI, I list all the peripherals that come back. But when one of them went down (we cut power to the radio), it stayed in the list, because there's no notification I know of for when it goes away. Am I overlooking something?
