    After my initial computations from Ed Cannon's observations, I
    discovered recently introduced errors in model, so I was just
    lucky that the solution was reasonable. New computations,
    including his approximate June observation, give an axis
    pointing to RA = 05:22, dec. -55.6  and a reflecting surface
    with its normal 82.45 degrees off-axis. More observations
    may prove the angle to be 90 degrees, and the axis at 05:10,-67.

    With SkyMap, insert the following lines into your deepsky.txt
    and observe BEFORE the point where the predicted track crosses
    the line between "I512/21" points. Plotting by hand, read the
    RA/dec values (decimal hours/deg) in col. 3/4.
