I have observed most of the Orbcomms at least once.  The brightness question
came up before and I did abit of testing.  The brightness depends critically
on the sun satellite observer angle in a way that, I think, is more
complicated than just the usual phase angle.  I can almost alway pick them
up in my 80mm telescope and, as a test, I specifically looked for them in
September with my 10 x 42 binoculars and was usuall able to see them.  I
have, however, missed them completely on several occasions.
