Friday night at SPOC we noticed a "constellation" of two satellites separated by only a couple of degrees, moving south-to-north, among several other single sightings.
For reasons that I assume are related to the low U.S. launch angle of satellites discussed in the S&T Oct issue article, I usually only see the north-south moving polar satellites, often during polar alignment. Except for the shuttle, I never see east-west movers. - Kurt _______________________________________________ Sent via CSolutions - http://www.csolutions.net
From my understanding, most satellites are north-south (south-north, mostly) movers, or are geosynchronous and thus not noticed casually due to a lack of movement. BTW, imaging geosynchronous satellites can be an interesting project; they tend to wander a bit as imaged against the stellar background.
