Comet Vozarova, formally designated C/1954 O1, is a possibly hyperbolic comet discovered by Slovak astronomer, Margita Vozárová, on 28 July 1954. The orbit calculation is based on 4 observations according to JPL, and the orbit may not be hyperbolic as according to the uncertainty the eccentricity could be between 0.6 and 1.5.
Discovery and observation
The comet was already on its outbound flight as a magnitude 9.0 object upon discovery,[6] where some observers noticed it also may have potentially fragmented.[4]
By August, the comet was found to have a 20-arcminute long tail pointed towards the Sun.[7] It was last observed from the Lick Observatory as a magnitude 18.5 object on 18 December 1954.[8][4]
