After reading Brad Sparks's analysis today, I think it is time for
me to recount my sighting of a Moby Dick balloon about 1956 in New
Orleans. I made lots of notes at the time, but am not sure where they
are now. So this is based on memory alone.
I was attending Tulane University (1954-1958). One day it was all
over the radio news that a brilliantly lighted object was hovering over
the city, so naturally between classes I went out to look. In broad
daylight, I think early afternoon, it looked like Venus at maximum
brilliance x4, seemingly much larger in apparent size than a star or
planet.
When I looked at it through 7 x 50 binoculars, I was surprised
that no shape could be resolved at all. It still looked like a
magnified version of Venus. I remember rushing home (I lived 15-20
blocks off campus) and setting up my 4-inch reflector telescope (I
don't recall which lens, maybe 125x) and managing to capture the object
in the field of view. Then I plainly saw the plastic balloon material
and the instrument package dangling beneath it. The balloon apparently
was becalmed because I don't recall that it moved very much if at all
during the 30-45 minutes I had it under observation.
Because it was brightly reflecting sunlight, it was visible for
many miles around. I have no idea how hih it was, though there was news
coverage about it next day with some further information. When a
plastic balloon of this size reflects sunlight, I'm sure it would be
visible for many tens of miles, and further might well evoke
comparisons to Venus unless someone happens to have a high-powered
telescope available. - Dick
