Hi John and others,
That last thing (most photographic orbits from 1953/54) I think is an
artifact of observing statistics. The years you mention belong to those that
produced most of the published Harvard Patrol orbits in the IAU database
(which form a significant part of the database content), and I reckon your
quoted orbits are mostly from this Harvard patrol indeed. But it does show
that a dedicated campaign with low light level video cameraas could prove
worthwhile for this stream.
