Popis:	Long-period comets have narrow 1-revolution old dust trails that can cause meteor outbursts when encountered by Earth. To facilitate observing campaigns that will characterise and perhaps help find Earth threatening long-period comets from their trace of meteoric debris, we use past accounts of outbursts from 14 different showers to calculate the future dust trail positions near Earth orbit. We also examine known near-Earth long-period comets and identify six potential new showers, which can be utilised to learn more about these objects. We demonstrate that it is the 1-revolution trail that is responsible for meteor outbursts. A method is presented that calculates in what year these showers are likely to return and at what hour. The calculations improve on earlier approximate methods that used the Sun's reflex motion to gauge the trail motion relative to Earth's orbit.
