BRANHAM JR, Richard L.. A New Orbit for Comet C/1830 F1 (Great March Comet). Rev. mex. astron. astrofis [online]. 2022, vol.58, n.2, pp.309-314.  Epub Mar 20, 2023. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2022.58.02.11.

Comet C/1830 F1 (Great March comet) is one of a large number of comets with parabolic orbits. Given that there are sufficient observations of the comet, (428 in right ascension and 424 in declination), it proves possible to calculate a better orbit. The calculations are based on a 12th order predictor-corrector method. The comet’s orbit is highly elliptical, e=0.99792 and, from calculated mean errors, statistically different from a parabola. The comet will not return for thousands of years and thus represents no immediate NEO threat.
