Good conditions until around 01:30UT when the sky clouded over. Unfortunately this was just before the first good pass of the OTV-5 candidate. Unknown satellite tracks were seen again. One was identified as SAR Lupe 2 [31797/07030A], and another as the NOSS 7 (A) [16591/86014A] candidate which I observed on April 8 as Unknown 99496/18598A. Starting from the classfd.tle elset I get this orbit: NOSS 7 (A) 1 16591U 86014A 18101.84513889 .00000000 00000-0 50000-4 0 00 2 16591 63.3055 104.5763 0908615 54.6603 13.7527 13.48718821 03 # 20180408.07-20180411.85, 17 measurements, 0.003 deg rms The third unknown [99499/18601B] seems to correlate with NOSS 2 (1977-112) objects, of which NOSS 2 (D) [10529/77112D] and NOSS 2 (F) [10594/77112F] are currently tracked. That leaves NOSS 2 (E) [10544/77112E], for which Mike McCants attributed my March 18 observations of unknown [99488/18577A] as that object. Unfortunately the 99488 and 99499 observations don't really provide a good fit to explain both sets of them as the same object... 16591 86 014A 4171 G 20180411201644661 17 25 1801801+590894 37 I 16591 86 014A 4171 G 20180411201645500 17 25 1802135+584999 37 I 16591 86 014A 4171 G 20180411201647179 17 25 1802789+581314 37 I 16591 86 014A 4171 G 20180411201649279 17 25 1803567+572795 37 I 16591 86 014A 4171 G 20180411201651099 17 25 1804190+564982 37 I 16591 86 014A 4171 G 20180411201653921 17 25 1805068+555305 37 I 16591 86 014A 4171 G 20180411201656201 17 25 1805761+550856 37 I 16591 86 014A 4171 G 20180411201659023 17 25 1806525+541505 37 I 16591 86 014A 4171 G 20180411201700706 17 25 1807011+534444 37 I 23605 95 033A 4171 G 20180411194731227 17 25 1739202+535734 37 S 28537 05 004A 4171 G 20180411235201857 17 25 2140542+590741 37 S 28537 05 004A 4171 G 20180411235210658 17 25 2140028+573732 37 S 28537 05 004A 4171 G 20180411235221619 17 25 2139441+554954 37 S 28537 05 004A 4171 G 20180411235231617 17 25 2139089+541580 37 S 28541 05 004C 4171 G 20180411235211299 17 25 2139864+582866 37 S 28541 05 004C 4171 G 20180411235221858 17 25 2139316+564229 37 S 28541 05 004C 4171 G 20180411235231617 17 25 2138964+550869 37 S 28541 05 004C 4171 G 20180411235239790 17 25 2138793+535304 37 S 31797 07 030A 4171 G 20180412011309954 17 25 2243200+564760 37 S 31797 07 030A 4171 G 20180412011311913 17 25 2249494+570398 37 S 31797 07 030A 4171 G 20180412011313894 17 25 2255886+571902 37 S 31797 07 030A 4171 G 20180412011315694 17 25 2301683+573158 37 S 31797 07 030A 4171 G 20180412011317814 17 25 2308483+574466 37 S 31797 07 030A 4171 G 20180412011320313 17 25 2316445+575793 37 S 31797 07 030A 4171 G 20180412011322873 17 25 2324427+580897 37 S 31797 07 030A 4171 G 20180412011325034 17 25 2331308+581707 37 S 36104 09 066A 4171 G 20180411203803381 17 25 1831175+593629 37 S 36104 09 066A 4171 G 20180411203809011 17 25 1847618+595691 37 S 40381 15 004A 4171 G 20180411203155316 17 25 1821136+534559 37 S 40381 15 004A 4171 G 20180411203157287 17 25 1826705+535775 37 S 40964 15 058A 4171 G 20180411223734535 17 25 2047657+602709 37 S 40964 15 058A 4171 G 20180411223741655 17 25 2045079+591265 37 S 40964 15 058A 4171 G 20180411223751635 17 25 2041779+573091 37 S 40964 15 058A 4171 G 20180411223801594 17 25 2038988+555251 37 S 40964 15 058A 4171 G 20180411223809273 17 25 2037155+543883 37 S 40964 15 058A 4171 G 20180412002843803 17 25 2233677+605262 37 S 40964 15 058A 4171 G 20180412002851604 17 25 2226008+593187 37 S 40964 15 058A 4171 G 20180412002901584 17 25 2217200+574767 37 S 40964 15 058A 4171 G 20180412002911564 17 25 2209471+560333 37 S 40981 15 058R 4171 G 20180411223742314 17 25 2046659+600710 37 S 40981 15 058R 4171 G 20180411223751635 17 25 2043389+583045 37 S 40981 15 058R 4171 G 20180411223801634 17 25 2040364+564968 37 S 40981 15 058R 4171 G 20180411223811734 17 25 2037733+551129 37 S 40981 15 058R 4171 G 20180411223817274 17 25 2036599+541854 37 S 40981 15 058R 4171 G 20180412002851823 17 25 2232152+602963 37 S 40981 15 058R 4171 G 20180412002901604 17 25 2222852+584804 37 S 40981 15 058R 4171 G 20180412002911584 17 25 2214526+570388 37 S 40981 15 058R 4171 G 20180412002919664 17 25 2208592+553965 37 S 41334 16 010A 4171 G 20180411201806173 17 25 1402969+283533 37 S 41334 16 010A 4171 G 20180411201808253 17 25 1400949+283200 37 S 41334 16 010A 4171 G 20180412012612363 17 25 1857675+233642 37 S 41334 16 010A 4171 G 20180412012618442 17 25 1855297+244327 37 S 99499 18 601B 4171 G 20180411195221270 17 25 1800455+600890 37 S 99499 18 601B 4171 G 20180411195222810 17 25 1750973+592618 37 S 99499 18 601B 4171 G 20180411195224330 17 25 1742009+584149 37 S 99499 18 601B 4171 G 20180411195225850 17 25 1733423+575435 37 S 99499 18 601B 4171 G 20180411195227250 17 25 1725848+570899 37 S 99499 18 601B 4171 G 20180411195228050 17 25 1721668+564238 37 S ------------------------------------------------------------------ Setup: Watec 902H2 video, 50mm F/1.8, NexStar mount, NTP timing IOD format: http://www.satobs.org/position/IODformat.html COSPAR 4171: 52.8344N, 6.3785E, 10m (WGS84) ------------------------------------------------------------------ Regards, Cees _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Thu Apr 12 2018 - 05:03:18 UTC
