I found the coordinates of the Altay optical/laser ranging centre (51°20' N, 82°10' E) here: http://cddis.nasa.gov/lw14/docs/papers/upg14_mbm.pdf Below is an ephemeris of the pass on which Lacrosse 2 was imaged, using near-contemporaneous hobbyist elements: 1 21147U 91017A 05226.90471059 .00000140 00000-0 20590-4 0 01 2 21147 67.9868 164.4138 0004000 260.5272 99.4728 14.75330661 01 14/ 8/ 5 00:00 - 24:00 UTC J2000.0 EL > 10 Altay Optical/Laser Lacrosse 2 91017A 21147 Bull = 0 Altay Optical/Laser SGP4 Age = -0.2 d Unc = 0 s ( 25%) Src = 1 TIME %I Mvv AZ EL R.A.
