Correction. I wrote: > the highfly.mag file is for objects with mean motion of 2 or less. Actually, Highfly will process objects with mean motion less than 9 (nine) revolutions per day. Quicksat processes only objects with mean motion 4 or greater. (So either program will give predictions for objects with mean motion 4 to 9.) Mike notes in the Highfly documentation that you can use the Quicksat.mag file with Highfly. Clarification. I wrote: > I don't know how to calculate the theoretical magnitude from RCS > and range. Well, I ought to, but anyway, Rob Matson wrote a full magnitude equation for "a spherical satellite with a perfectly Lambertian surface" in this message: http://www2.satellite.eu.org/seesat/Apr-2001/0313.html Observations. Last night once more, NOSS 2-2 trio was one power, from the middle of the city. During the part of the pass that I saw they were fainter than the previous two reports, but I missed the pre-culmination part of the pass due to being rudely distracted by 00694 (63-047A, the oldest Atlas Centaur in orbit). As the NOSS 2-2 trio were nearing one of the bright stars in the south, a west-to-east satellite crossed just to the south of them. While watching Superbird A flash itself silly once again, a flock of birds heading north crossed with it right about click #33! Only a few minutes later our late-night low clouds came in on the sea breeze from the Gulf of Mexico.
