Had a good pass this evening just after nautical twilight. Seen visually, but much fainter than I expected, only reaching about mag +4 (to be checked on my video). A few folks I mentioned it to failed to see it at all. Here is the Quicksat ephemeris for Coonabarabran, NSW for this evening's pass. We have a near overhead pass tomorrow in bright twilight close to the nominal reentry time (currently with large uncertainty) 63801 0 SZ-19 DEB SZ-19 DEB n=16.33 e=0.0005 i= 41.5 ( 181 * 188 km ) Orbit epoch = 70.974 Predi epoch = 71 H M S Tim Al Azi C Dir Mag Dys F Hgt Shd Rng EW Phs RA Dec 09:23:33 6 243 12 25.4 0 7 186 163 998 0.9 155 0004 -26.4 09:23:42 7 243 14 24.8 0 7 186 157 934 0.9 154 0008 -26.7 09:23:51 9 244 9 24.2 0 7 186 150 871 0.9 153 0014 -27.0 09:24:00 10 244 16 23.8 0 7 186 143 807 1.0 153 0020 -27.4 09:24:09 11 244 17 23.3 0 7 186 135 744 1.1 152 0027 -27.7 09:24:18 13 245 19 22.8 0 7 186 127 681 1.2 150 0034 -28.1 <- failed to see it visually down here 09:24:27 15 246 20 22.3 0 7 186 117 618 1.3 149 0044 -28.4 09:24:36 17 246 19 21.8 0 7 186 107 557 1.4 147 0055 -28.8 09:24:45 20 248 21 21.3 0 7 186 97 496 1.6 145 0108 -29.1 09:24:53 23 249 21 20.7 0 7 186 85 437 1.8 142 0125 -29.3 09:25:02 28 251 22 20.1 0 7 186 73 380 2.2 138 0147 -29.4 09:25:11 34 254 25 19.5 0 7 186 60 326 2.7 132 0216 -29.1 <- around mag +4 here 09:25:20 41 259 28 18.8 0 7 186 47 276 3.6 125 0255 -28.0 09:25:29 51 267 35 18.1 0 7 186 32 235 4.8 114 0347 -25.4 09:25:38 63 287 51 17.5 0 7 185 17 207 6.1 99 0451 -20.3 09:25:47 69 332 C 93 17.2 0 7 185 2 198 7.0 82 0602 -12.4 09:25:56 62 14 132 17.1 0 7 185 -14 210 6.7 65 0707 -3.4 Cheers, Rob On 9/03/2026 10:11, Marco Langbroek wrote: > Op 9-3-2026 om 10:24 schreef Robert McNaught via Seesat-l: >> Observed scooting along in twilight at Alt 10deg Az 164 at mag +4 >> steady (10x42B) >> 2026 Mar 09 09:13.6UT >> exactly on prediction from latest elements (epoch 26067.966, 16.22 >> rev/day, 217x219km) with reentry expected in about 3 to 4 days >> according to SpaceTrack. >> >> Cheers, Rob >> Coonabarabran, NSW, > > > Our current TU Delft Tudat reentry prognosis for this object is: > > 13-03-2026 10:12 +- 21.4 h UTC > > see https://reentry.langbroek.org > > - Marco > > > ------ > Dr Marco Langbroek > Lecturer in optical Space Situational Awareness (SSA) > > TU Delft, Faculty of Aerospace Engineering > section Astrodynamics and Space Missions > ------ > _______________________________________________ Seesat-l mailing list https://lists.seesatmail.org/mailman/listinfo/seesat-lReceived on Thu Mar 12 2026 - 03:03:22 UTC
