I'm not sure why Spacecom is predicting reentry over Antarctica -- that's one of the least likely places for it to come in owing to the lower radius of the earth at the poles (and thus higher altitude of the satellite). One rev prior to the middle-America pass, there is also a pass that goes over Maine at ~7:01 UT tomorrow (2 am local time). This southbound pass would also be visible from Boston, perhaps as high as 30 degrees above the eastern horizon. The middle America pass flies over NE Minnesota, Wisconsin, SE Missouri, the Ark/Tenn border, Mississippi and the southeast tip of Louisiana (i.e. New Orleans). If Iridium 79 can hold on for one more rev, western Montana, eastern Idaho, central Utah (Salt Lake City) and central Arizona (Phoenix, Tucson) are on the flight-line. Salt Lake City is directly on the orbit ground track. Phoenix is somewhat to the west of it; Tucson is closer, but east of the groundtrack. Southern locations would be favored over northern ones, again owing to the earth's oblateness. --Rob ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
