Tony Beresford has a file of orbital elements of a number of this type of object (plus a few other flashers that are in highly eccentric orbits): http://www.adelaide.net.au/~starman/tle/geoflsh.tle To those I'll add the following others that I have seen or that have been reported on SeeSat: 11841 80049A Gorizont 4 15677 85035A GSTAR 1 17046 86082A Raduga 19 17083 86090A Gorizont 13 18631 87100A Raduga 21 19017 88028A Gorizont 15 19483 88081A GSTAR 3 19919 89027A Tele-X 20705 90063A TDF 2 90007 00653A Unknown Several of the above are included in the mccants.tle file: http://users2.ev1.net/~mmccants/tles/mccants.zip I've seen Superbird A, the two GSTARs, Tele-X, TDF 1 and TDF 2, and a couple of Gorizonts without magnification. 90007 flashes to at least +4, but it's now among the missing due to too much unfavorable weather over Austin. Note that many of these flash at their brightest, like Superbird A, for only a few minutes each night. More information, though getting somewhat dated, on this type of object is on the following Web pages: http://www.geocities.com/CapeCanaveral/Hangar/1668/geo-ppas.htm http://www.geocities.com/CapeCanaveral/Hangar/1668/gorizont.htm Other high-altitude eccentric flashing objects include several Molniyas, 90006, 90907, Hipparcos, Centaurs. Most of these usually require a telescope but can sometimes be seen with binoculars. A few Molniyas have been seen without magnification on rare occasions.
