Interestingly enough, during the next pass (21:03-21:20 UT), just north of the zenith at very high elevation, almost all Starlink sats were very dim: most NOT seen by naked eye, with a handful of notable exceptions. Goes to show that satellite orientation and relative angle of sun-sat-observer are very important, and should be taken into account when discussing visibility issues. I have noted before, with other Starlink "trains", that passes in the zenith are often faint, while passes lower in the sky are brighter. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Tue Apr 21 2020 - 06:47:54 UTC
