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
George van Biesbroeck
concluded they were different comets.
The 1935 approach was observed though not as favourable, in 1937 the comet passed close to
perihelion distance and orbital period
.
Due to miscalculations, the 1942 appearance was missed, but it has been observed on every subsequent appearance since.
The comet nucleus is estimated to be 7.8 kilometers in diameter.[4]
