First calculations of orbit concluded a period of 25 years, but this was revised down to seven years and speculation this was the same comet as Comet Taylor, which had been lost since 1915. Further calculations by George van Biesbroeck concluded they were different comets.
Due to miscalculations, the 1942 appearance was missed, but it has been observed on every subsequent appearance since.
