27984 Herminefranz           Discovered 1997 Nov. 1 at the Starkenburg Observatory, Heppenheim.
Hermine (b. 1954) and Franz Stoss (b. 1950) are the parents of Reiner Michael Stoss, discoverer of this minor planet. They have strongly supported their son's activities in minor planet work at the Starkenburg Observatory, Heppenheim. The family emigrated from the Banat region to Germany in 1987.
