(3982) Kastel

P. Pravec and P. Kusnirak, Ondrejov Observatory; L. Kornos and J. Vilagi, Modra Observatory; D. Pray, Coventry, RI; R. Durkee, Minneapolis, MN; and W. Cooney, J. Gross and D. Terrell, Sonoita Research Observatory, AZ, report that photometric observations obtained during Sept. 24-29 reveal that (3982) has a lightcurve consisting of two linearly additive components with periods 8.488 and 5.835 (or possibly 2.918) hr and amplitudes 0.27 and 0.08 mag, respectively. No attenuations due to occultations/eclipses were seen, so the proposed interpretation of binary nature of the minor planet needs to be confirmed with further observations.
