Camera at manual mode, "10 second" (= 10.7 second) exposure, wide field f2.8/7.41 mm. What these numbers mean: http://www.satobs.org/position/IODformat.html ------------------------------------------------------------------------- Clear sky, but a bit bright due to moonlight. Observed two passes of Lacrosse 5 and one of USA 186 and Lacrosse 2. Tried USA 129 as well but it was too faint. 05-042A (USA 186) made a bright -1 flare at 21:01:10 UTC, some 10 seconds before the camera opened. I only measured the bright startpoint of the fading trail on the image. The sat was on-time. 05-016A (Lacrosse 5) was some 0.4s late. 91-017A (Lacrosse 2) was 2.3s early. Lacrosse 5 did a short "disappearance trick" early in the second pass. I saw it at about 21:30:00 UTC, then it went gone at about 21:30:15 UTC if memory serves me correct, to re-appear again very brightly at about 23:31:00 UTC, remaining visible untill it went into earth shadow. - 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
