256 Walpurga is a large Main belt asteroid. It was discovered by Johann Palisa on April 3, 1886 in Vienna and was named after Saint Walburga.
Photometric observations at the Oakley Observatory in Terre Haute, Indiana during 2007 were used to build a light curve for this asteroid. The asteroid displayed a rotation period of 16.64 ± 0.02 hours and a brightness variation of 0.38 ± 0.02 in magnitude.[1]
