Scientific paper

The asteroid 476 Hedwig was observed photoelectrically in UBV from March 27 to April 1, 1982 using the ESO-0.5 m telescope at the European Southern Observatory, La Silla, Chile. On the basis of six consecutive nights of observations, we derive a rotation period of P = 27.h33 ± 0.h04 (= 1.d139 ± 0.d002) and a lightcurve amplitude of 0.m13. The lightcurve shows primary and secondary extrema. UBV-colours were measured continuously and no colour variation exceeding the scatter could be found.
