The sky cleared abit during the night, but still alot of thin and some thicker clouds.In the clearings several satellites were imaged, A nice pass of the 10 new Iridium satellites was clouded out. Several satellites have higher residuals due to older TLE's; see below. 12553 81 059A 4172 G 20171228043127968 17 25 1657015+492380 37 S 12553 81 059A 4172 G 20171228043133945 17 25 1645892+484607 37 S 20691 90 050C 4172 G 20171228043321953 17 25 1705140+534025 37 S 20691 90 050C 4172 G 20171228043331959 17 25 1658992+505287 37 S 20691 90 050C 4172 G 20171228043340877 17 25 1654411+482808 37 S 20692 90 050D 4172 G 20171228043401959 17 25 1657760+515256 37 S 20692 90 050D 4172 G 20171228043411961 17 25 1652412+490976 37 S 28353 04 021B 4172 G 20171228043441961 17 25 1701113+535504 37 S 28353 04 021B 4172 G 20171228043451957 17 25 1649809+505545 37 S 41334 16 010A 4172 G 20171228050342950 17 25 1418561+100395 37 S 41334 16 010A 4172 G 20171228050351957 17 25 1409869+085987 37 F 41334 16 010A 4172 G 20171228050401954 17 25 1400270+074835 37 S 41334 16 010A 4172 G 20171228050408157 17 25 1354486+070210 37 S 23533 95 015A 4172 G 20171228052451979 17 25 1434154+210255 37 S 23533 95 015A 4172 G 20171228052501977 17 25 1424742+180053 37 S 23851 96 024A 4172 G 20171228052721980 17 25 1322324+230976 37 S 23851 96 024A 4172 G 20171228052730982 17 25 1315783+200775 37 S Obs format: http://www.satobs.org/position/IODformat.html Residuals wrt the latest classfd.tle file before the session start.
