Reports from Geisei Observatory <February 18, 2011>


Observations made with the 60cm reflector and not previously reported (2)

    Continued from the previous report, these are the measurements made from earlier observations using the 60cm reflector. As the films are already more than 10 years old, the images have faded and generally appear faint. However, I am certain the precision of positional measurements is maintained.
    Photographs taken for comet patrol often show the targeted objects near the edge of a frame, which, together with coma, may result in less precise measurements. SL590 is a minor planet moving east between two galaxies in Leo. As it passed opposition some time ago, it is in direct motion.

    Two of the objects reported above are identified as follows by Mr. Hirohisa Sato.
     SL589 = (6216) San Jose
     SL590 = (2965) Surikov
