226 Weringia

226 Weringia is a typical main-belt asteroid. It was discovered by Johann Palisa on 19 July 1882, and was named after Währing, part of Vienna, the city where the asteroid was discovered. Photometric observations during 2008 showed a rotation period of 11.1496 ± 0.0009 hours and a brightness variation of 0.20 ± 0.02 in magnitude.^[2]
