1806 Derice, provisional designation 1971 LC, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. Discovered on 13 June 1971, at the Bickley site of the Perth Observatory in Western Australia, it was the first discovery of a minor planet ever made in Oceania. The asteroid was named after the wife of Dennis Harwood, staff member at Bickley.[2][10]
