A new orbit is calculated for Comet C/1861 J1 (Great comet of 1861) to replace Kreutz?s orbit of 1880. The orbit is based upon 2,362 observations, 1,198 in right ascension and 1,164 in declination, made between May of ...

Comet C/1854 L1 (Klinkerfues) is one of a large number of comets with parabolic orbits. Given that there are sufficient observations of the comet, 262 in right ascension and 260 in declination, it proves possible to calculate ...

Comets C/1848 P1 (Petersen) and C/1848 U1 (Petersen) are ones of a large number of comets with parabolic orbits. Given that there are sufficient observations, 67 in right ascencion and 61 in declination for the former and ...

A new orbit is calculated for Comet C/1819 N1 (Great Comet of 1819) to replace Peck’s parabolic orbit of 1906. The orbit is based upon 402 observations in right ascension and 294 in declination, made between July and October ...

Comet 17P/Holmes was observed in October and November 2007, after the brightness outburst of 24 October. Approximately 11.5 hours of data were collected. A time series analysis reveals a periodicity of 6.29±0.01 hour in ...
