Did An Alien Probe Pass Earth In 1991?

What does one do for an encore after posting `A Roswell Alien' AND a `Crashed UFO with living alien' videos yesterday? (cough-cough) - Simply provide a link to a Harvard paper suggesting that an alien probe passed Earth 20 years ago (checking on us?) and will return in 2016 - http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1995Obs...115...78S&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf
but, as Clockers know, it is never quite that simple - here's another suggestion, actually a whole discussion,  of what it might be - http://www.bautforum.com/archive/index.php/t-73032.html - and these are some background, first, into the background of the author - http://en.wikipedia.org/wiki/Duncan_Steel and the source of where I found this link on Reddit - http://www.reddit.com/r/UFOs/comments/h4onz/crosspost_from_til_alien_probe_may_have_passed/
simple, right?
===============================
BTW, if you were wondering where the comments about the Roswell Alien Video and the Crashed UFO Video stand today - here you go - http://www.latest-ufo-sightings.net/2011/05/leaked-video-of-roswell-grey-alien.html#comments
================================
And, finally for today - http://www.youtube.com/watch?v=QUWB7x9jhEc&feature=player_embedded - in what I assume to NOT be real - 5 Orbs in the sky doing something that I have never seen. If the goal is to make those that care even a smidgen about this subject become jaded - more like this video will be common place.

Thanks for your visit today.
