摘要：

The outburst of the Phoenicids observed in 1956 was investigated on the basis of the dust trail theory by using a newly linked orbit, which was estimated from the asteroid 2003 WY25 and comet D/1819 W1 (Blanpain). We found that a bundle of the trails formed from the late 18th through the early 19th centuries came close to the Earth's orbit at the epoch of the outburst in 1956. According to similar calculations for 1950-2030, the situation in 1956 was proven to be the best epoch for a strong display in the Phoenicids. This result shows not only a definite association of the objects to the Phoenicids, but also a clear reason for the sudden outburst in 1956. Although future activity is expected in 2014, it depends on the cometary activity of the parent object, because the related trails are expected to be relatively new.
