Camera at manual mode, "10 second" (= 10.7 second) exposure, wide field f2.8/7.41 mm. What these numbers mean: http://www.satellite.eu.org/position/IODformat.html In a sky with a touch of haze I catched Lacrosse 2 (91-017A) while flaring to mag -1.5 at 21:54:48 UTC. Very well defined trail on the image. Cross-track error is 0.05-0.06 deg., which is a true deviation imho as it is too large to be a measurement inaccuracy, especially given the fine trail image and other fit results. Reference star position consistency 22", delta T is 0.02 resp. -0.01 sec relative to elset 06159.92449946, overall positional error relative to this elset 0.050 resp 0.057 deg, cross-track in this case. Observations were done with a pleasant outside temperature of +24.5 C. - Marco :-) ----- Dr Marco Langbroek - SatTrackCam Leiden, Cospar 4353 Leiden, the Netherlands. 52.15412 N, 4.49081 E (WGS84), +0 m ASL SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com Atom RSS: http://sattrackcam.blogspot.com/atom.xml e-mail: sattrackcam@wanadoo.nl ----- ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
