Comet Vozarova, formally designated C/1954 O1, is a hyperbolic comet discovered by Slovak astronomer, Margita Vozárová, on July 28, 1954.
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 December 18, 1954.[8][4]
