  • CBET No. 1716, 2009 March 11 – Central Bureau for Astronomical Telegrams for (4607) Seilandfarm:
    Photometric observations obtained between 17 January and 25 February 2009, show that 4607 Seilandfarm is a binary system with an orbital period of 31.63±0.02 hours. The primary has a period of 3.9683±0.0001 hours, and it has a lightcurve brightness variation of 0.15 magnitude, indicating a nearly spheroidal shape. Mutual eclipse/occultation events suggest a lower limit on secondary-to-primary mean-diameter ratio of 0.29.Central Bureau for Astronomical Telegrams No. 1716
