The Case of Comet Lowe 1913 I

The unconfirmed Comet Lowe 1913 I has a minimum distance between its
orbit and that of the Earth (MOID) which is smaller than 1.000.000,00 km
for some values of T and e chosen, also using various orbital elements
which are slightly different from those compiled from the literature. A
possible previous passage was uncovered, and we suggest a non-recognized
meteoric shower. The impossibility to write up reliable ephemerids
renders this comet a potentially dangerous object for the possibility of
collision with the Earth with a short period of warning.
