289P/Blanpain

289P/Blanpain, formerly D/1819 W1 (Blanpain) is a short-period comet that was discovered by Jean-Jacques Blanpain on November 28, 1819. Blanpain described the comet as having a "very small and confused nucleus". Another independent discovery was made on December 5 of that year by J. L. Pons. Following this the comet was lost, and was given the designation 'D' (Disappeared or Dead). However, in 2003, the orbital elements of newly discovered asteroid were calculated by Marco Micheli and others to be a probable match for the lost comet. Further observations of the asteroid in 2005 by David Jewitt using the University of Hawaii 2.2 m telescope on Mauna Kea, appeared to reveal a faint coma, which supports the theory that is the lost comet, or a part of it. The comet was officially established as periodic comet 289P in July 2013, after being rediscovered by the Pan-STARRS survey during an outburst event.
289P will be best viewed near and after the 2019-Dec-20 perihelion passage.
Source of Phoenicids.
Comet D/1819 W1 has been proposed as the probable source of the Phoenicid meteor stream, since the first observation of a Phoenicids meteor storm in 1956. Analysis of the orbits of asteroid have supported this conjecture, and it is thought likely that the comet was already breaking up at the time of its 1819 return. The comet currently has an Earth-MOID of .
