199950 Sierpc           Discovered 2007 Apr. 16 at the Astronomical Research Institute in Charleston.
Sierpc is one of the oldest towns in the Mazovie Region of Poland, established at the turn of the 11th century. It is situated at the crossroads of Prussia and Cracow, and is a pivotal railway junction in Poland. Since 2007, high schools in Sierpc have been active in minor-planet discoveries as part of IASC.
