Normally, the September epsilon Perseids meteor shower (SPE) produce a peak of around 5 meteors per hour at maximum. This year, with a 60 percent illuminated moon rising near 22:30 (10:30pm) local summer time, one could easily dismiss the probably of seeing anything extraordinary from this source. Yet interplanetary dust expert Jérémie Vaubaillon has brought to our attention that the Earth may pass through debris streams that were produced by an unknown source in 1375 and 1848. The timing of these passages occurs on September 9 near 9:55 universal time (4:55am CDT) for the 1848 stream and 13:32 universal time (11:55pm HST on Sept. 8) for the 1375 stream. These times favor North America for the first encounter and the eastern Pacific area for the second encounter as it will be daylight across the European continent. The density of these streams is unknown so predictions of meteor activity can only be a guess. The best advice is to expect nothing at all and hope for the best!
On the night of maximum activity, the radiant for the September epsilon Perseids lies at 03:12 (048) +40. This position is easy to locate in the sky as it lies only one ...
