Imaged USA 21, the last of the SDS-1 launched in a Molniya orbit, which I had not noticed as matching up well with 90083 that was tracked since 2009. At some point, it was removed from classfd.tle but I don't have record of when. It looks like Peter Wakelin first ran across it: http://www.satobs.org/seesat/Jan-2009/0282.html Elsets began appearing soon after: http://satobs.org/seesat/Mar-2009/0006.html I first saw it in August 2009, even showing it to star party guests: http://www.satobs.org/seesat/Aug-2009/0195.html Greg Roberts was still reporting it as an unknown in 2018: http://www.satobs.org/seesat/Mar-2018/0084.html Unknown 090126 (90083 / 09526A) = USA 21 (17506 / 87015A): 17506 87 015A 7779 G 2020051205430901 17 25 1507047+001542 16 S+167 10 17506 87 015A 7779 G 2020051205440901 17 25 1508480+012402 16 S+166 10 ISON (62800 533 days since last amateur report, 141410 121 days): 62800 50 016A 7779 G 2020051206050299 17 25 1822238+000543 16 S+188 10 62800 50 016A 7779 G 2020051206060299 17 25 1822885+000591 16 S+190 10 99999 99 999A 7779 G 2020051205375098 17 25 1501607+050969 16 S+172 10 99999 99 999A 7779 G 2020051205385098 17 25 1502586+050509 16 S+171 10 99999 99 999A 7779 G 2020051205395798 17 25 1503708+045994 16 S+171 10 99999 99 999A 7779 G 2020051205405798 17 25 1504683+045538 16 S+163 10 99999 = ISON 141410 Unclassified (Viasat 2 r/b, 42742 new to me): 29274 06 033C 7779 G 2020051206344101 17 25 1207762-114913 16 S+152 10 29274 06 033C 7779 G 2020051206354101 17 25 1209198-115051 16 S+156 10 42742 17 029C 7779 G 2020051206323504 17 25 1212073-124791 16 S+141 10 42742 17 029C 7779 G 2020051206333504 17 25 1213658-125796 16 S+147 10 42742 17 029C 7779 G 2020051206344101 17 25 1215441-130924 16 S+146 10 42742 17 029C 7779 G 2020051206354101 17 25 1217091-131981 16 S+143 10 Thanks Ted, for helping fix the spreadsheet utility, works great!
