J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. A Dutch meteor researcher for more than 20 years, Urijan Poerink (b. 1953) was particularly involved in expeditions to southern France for observing the Perseids in 1993 and to South Korea, Jordan and Spain for the Leonids during 1998-2002. The name was suggested by H. van Woerden, S. van Leverink and A. van der Brugge.
