I usually see them shortly after dusk, but morning as well. I assumed it was bc I sleep from 10-6, but the Sun placement makes sense. Thanks for that tidbit. As far as groups, they are rarely in sequence. Sometimes I see two aligned and just offset. Usually they are flowing in generally the same N-S direction with one or two seconds behind the other. The E-W satellites seem much more rare. Pardon my ignorance. I have no formal training, just a Sky gazer and mediocre Googler.
