120349 Kalas           Discovered 2004 Dec. 12 at Jarnac.
John (b. 1948) and Elizabeth (b. 1949) Kalas are active in proselytizing the night sky at public events. John has demonstrated to hundreds of youth groups his specialty of displaying solar activity in H \alpha . In addition to assisting her husband on crowded evenings, Liz fashions blankets worthy of awards.
