The above accounts for less than 5 % of the whole sample." The object on the photo looks like pieces of industrial slag I have seen. So that would be my first interpretation of it, rather than space debris, unless something in the composition/morphology suggests otherwise and clearly connects it to space debris. Note that each year I get several reports (as potential "meteorites") of objects that did damage, including objects that went through windows. Invariably it is accompanied by "reasons" (as in the BAA article) why it/the damage "cannot" have a terrestrial origin. Over the past 20 years none of it however was a genuine meteorite or space debris. So be careful there. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL Cospar 4355 (Cronesteyn): 52.13878 N, 4.49937 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek PGP key: http://tinyurl.com/kur7xm8 ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Wed Dec 31 2014 - 04:33:41 UTC
