Long Intervals are when the Red Star doesn't pass close enough to Pern to drop Thread on the planet. Four hundred years pass without any Thread. The Ninth Pass comes immediately after a Long Interval, and at the end of the before-mentioned Long Interval, many believed Thread would no longer come back, but it did.
