Thanks for searching Rob - Well, Ive seen afew Iridiums and it was too slow
moveing to one of those. Also Ir sats are visable after a flare at my dark
location. This object went invisable, and never came back.

 Its speed was more like the old Pageos balloon sat.
Indicating high altitude. Maybe 'll look for some elements for Pageos
fragments and plug them in to my good ole "Mr Orbit" program.   :-)

Its fascinating to see some unknown object - maybe debris - that is never
seen except for now and then when it aligns itself with the sun and my
location to show itself so well.

The sky may have many objects like this, and we will just have to wait for
the next unscheduled treat!

 Again, thanks for trying -  Jim
