3637 O'Mera: New Binary Candidate
Abstract
CCD photometric observations made in 2016 August and September of 3637 O'Meara give some indications that this object could be a binary asteroid. Under the hypothesis that the binary interpretation is correct and not due to a systematic effect, the data suggest the primary lightcurve could have a period of 4.118 °± 0.001 h and an amplitude of 0.25 °± 0.09 magnitudes. The orbital period of the satellite could be 13.8252 ± 0.0021 hours. Based on mutual events ranging from 0.28 to 0.33 mag, the estimated effective diameter ratio of the two bodies is Ds/Dp . 0.59 °± 0.07.
