The evidence supporting this stream’s existence is scant, but what makes it most interesting is that the available observations seem to point to a fairly short-duration shower. The greatest support for this stream appeared during Zdenek Sekanina’s 1969 session of the Radio Meteor Project. A total of 32 meteors were detected during January 13-17 from an average radiant of RA=245.9°, DECL=+62.4°.
Possible visual observations are rare, possibly due to the short duration. During the 19th century, Giuseppe Zezioli (Bergamo) plotted several meteors during January 16 of the years 1867-1869, which Schiaparelli derived a radiant of RA=244°, DECL=+64°, while W. F. Denning’s investigation of the records of the Italian Meteoric Association revealed six meteors plotted from RA=241°, DECL=+63°, during 1872 January 1-15. During this century observations have also been scarce. R. Kingman (Bristol, England) plotted 6 meteors from RA=245°, DECL=+64°, during 1928 January 16-24. In Hoffmeister’s 1948 book Meteorströme, a radiant designated 2877 was observed on 1937 January 13, from a position of RA=236 deg, DECL=+59 deg.
Among all of the photographic lists, only two meteors appear in a paper by R. McCrosky and A. Posen in 1961. Designated 6112 and 10081, they were detected on 1953 January 13 and 1954 January 13, respectively, and indicate an average radiant of RA=236°, DECL=+59°. Although the orbit is very similar to that determined by radar, the orbital inclination is about 15° greater.
