Discovered on 24 October 1995 by D. di Cicco at Sudbury.
One of the premier astronomical organizations, the American Association of Variable Star Observers (AAVSO) was founded in 1911 by amateur William Tyler Olcott, following Harvard astronomer Edward C. Pickering's prescient vision of a collaboration between amateurs and professionals in the name of science.Naming citation (20030501/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
