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]
