In fact it *theoretically* is, attaining a maximum sky elevation of about 12 degrees in the SW some 6 minutes after launch, if my launch trajectory reconstruction is realistic. But the whole launch trajectory is NOT illuminated by the sun, so no sunlit exhaust clouds and sunlit rocket. All the light has to come from the rocket engine, at 1000+ km. And given that LauncherOne is not a very big rocket (and by the time it rises over the horizon for Belgium, the first stage already will have burnt out), that makes it more problematic, although perhaps not impossible (with optical aid). - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org launchtower: http://launchtower.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 Mon Jan 09 2023 - 11:58:26 UTC
