C/1932 M2 Geddes
more info
Comet C/1932 M2 was discovered on 22 June 1932 by Murray Geddes (Otekura, New Zealand), that is one month before perihelion passage, and the comet was last seen on 19 July 1934 [Kronk, Cometography: Volume 3].About a year after its discovery, the prediscovery images on plates exposed on 14 August 1931 (at Bloemfontein, Harvard University Station in South Africa) were found.
This comet made its closest approach to the Earth on 1 July 1932 (1.97 au), that is nine days after its discovery.
Solution given here is based on data spanning over 2.93 yr in a range of heliocentric distances from 4.78 au through perihelion (2.31 au) to 6.83 au.
This Oort spike comet suffers small planetary perturbations during its passage through the planetary system; however, they led to escape the comet from the planetary zone on a hyperbolic orbit (see future barycentric orbit).
C/1932 M2 was in the original sample of 19 comets used by Oort for his hypothesis on LPCs; however, according to presented here statistics for previous perihelion passage its dynamical status is uncertain.
