Donald Machholz of Colfax, California, an optician who
has been interested in astronomy since age eight,
discovered nine comets from 1978 through 1994. He
has since spent 1,457 hours scanning the skies for
other comets, without any luck. Machholz spotted the
comet through the 30X eyepiece of his 6-inch f/8
Criterion Dynascope Newtonian reflector, a vintage
telescope that was a mainstay among amateur
astronomers during the 1960s and 70s. Machholz had
purchased his back in 1968.

73P/Schwassmann-Wachmann, (images on the right
& below)
also known as Schwassmann-Wachmann 3,
is a periodic comet in our solar system which is in the
process of disintegrating.
The comet was initially discovered by Arnold
Schwassmann and Arno Arthur Wachmann on May 2,
1930. It has an orbital period of slightly less than 5 1/3
years so that it comes nearest to the Earth every 16
years.

Sekanina (1989) estimated a pre-breakup (prior to
1995) diameter of about 2 km.
Toth et al. (2005) estimate that fragment C (prior to
recent splitting) had a diameter of 1.3 km.
