Greetings, all! I've been reading SeeSat-L for a few months now, and contributing a bit, but the recent rash of introductions from new readers has made me think that I should introduce myself, as well. My name is Roland Vanderspek, and I am on the research staff at the Massachusetts Institute of Technology. I worked on the recently launched-but-not-released HETE payload (launched Nov. 4, 1996 on a Pegasus XL). My experience with viewing satellites is not visual, but rather through an instrument called the Explosive Transient Camera (ETC). The ETC is an automated instrument, located on Kitt Peak, near Tucson, Arizona: its mission is to detect and record images of short-duration optical transients, preferably those from astrophysical sources. Readers of this list will guess, though, that what the ETC sees most is satellites. We see point-like sources, streaks, well-spaced collinear points, and slowly-moving objects varying in brightness: all in all, quite a menagerie. For us, these observations are noise, and we're most happy when we can recognize and throw out observations of satellites, but we haven't been able to do this with 100% effectiveness. Through this group, I'm beginning to learn more about new ways of attacking this problem, but I still hold out little hope that I can identify all my mystery objects. I'll go back to my read-only mode now... Roland
