    On April 15, 2005 UT Magdalena occulted a 10.7 mag star in the constellation Scutum for observers along a path across Australia.

    Measurements made with the IRAS observatory give a diameter of 106.08 ± 0.25 km and a geometric albedo of 0.03 ± 0.01. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 105.32 ± 11.11 km and a geometric albedo of 0.03 ± 0.01.[3]

    Alternative Rock group The Pixies named one of their songs after the asteroid on their album Indie Cindy.
