Halton C. Arp
is one of the key actors in the contemporary debate on the origin and evolution of galaxies in the universe. His
landmark compilation of peculiar galaxies, the Atlas
of Peculiar Galaxies, led him to challenge the fundamental assumption
of modern cosmology, that redshift is a uniform indicator of distance. He continues the search at the Max
Planck Institute for Physics and Astrophysics.
The Astronomical League's Arp Peculiar Galaxy Club is based on the 338 objects found
in the Arp Catalog of Peculiar Galaxies. To qualify for the AL's Arp Peculiar Galaxy Club Certificate, you need
only be a member of the Astronomical League, either through an affiliated club or as a Member-at-Large, and image
100 of the 338 objects in the Arp Peculiar Galaxy Catalog. You may select which 100 objects that you want

Dear Mr. Wagoner,
Just found the AAAA Arp Page with the Knauss-Morton images. What a great thing!
I am in the process of auditing my Arp list and have found a number of corrections, after reviewing the Arp views
in the Vickers' Atlas and the Carnegie Atlas, hunting elusive compnaion names and comparing with the Hickson list
of Compact Galaxy Groups, as well as incorporating some appropriate Mitchell Anaonymous Catalog entries. I will
provide you with an update to the AL online materials, when I get done. Most corrections are to fainter galaxies.
