Reports from Geisei Observatory <September 21, 2013>

C/2013 R1 (Lovejoy)

    C/2013 R1 Lovejoy was observed at Geisei Observatory. Our observation of this comet is presented in the Circumstances of New Astronomical Object Discoveries?h by Mr. Hirohisa Sato, Director of OAA Comet Section.
    This comet is expected to approach the earth in December and become a binocular comet at 7th to 8th magnitude. This brings back the memory of Comet Lovejoy, a Kreutz sungrazer, discovered in the previous year.
    The photograph below was taken with a 3-minute exposure using Geisei's 70cm reflector. The total magnitude is 12 and a very faint tail is visible to the right (west).
