What are the objects designated as USA ###<(two or three digit number)? Are they just unidentified (obviously US) satellites? I see the Lacrosse radar imaging satellites listed often in the elsets, but rarely see visual imagery satellite(s) (like the KH series) listed. Why is this? Is it because they change their orbit more often or more radically and are lost to amateur observers? Also, is there a list somewhere that identifies which of the _many_ cosmos objects are intelligence gathering satellites? Sorry for the basic questions, but this is a new area for me that I haven't paid much attention to before. Until now, any bright satellite, flasher, or NOSS formation has been my primary source of entertainment.
