Obs SatTrackCam Leiden (Cospar 4353), 15 Jan 2007: 28646 05 016A 4353 P 20070115175546100 17 75 2048372+760700 56 S+025 10 28646 05 016A 4353 P 20070115175556800 17 75 2059108+811920 56 S+025 10 ------------------------------------------------------------------------- Method: Canon Digital Ixus 400 + ASTRORECORD astrometric software. 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 A poor evening after a nice day. Late in the afternoon and in the early evening cirrus moved in, after it was nice and clear earlier, allowing a rare view of a daylight comet. Due to the cirrus, Lacrosse 5 (05-016A) was the only of 3 sats I tried this evening that was captured. The first point might be a bit iffy, the second is good I think. delta T is similar to yesterday (+0.2s). Shortly after this exposure, Lacrosse 5 "disappeared" again. This happened between 17:56:00 and 17:56:30 UTC (I did not see it disappear as I was handling the camera, but when I looked up again after triggering the 2nd image it was gone visually, and it is not visible on the 2nd image either). At 14:35 local time (CET) during the clear part of the day, I managed (with difficulty, but certainty) to observe comet C/2006 P1 McNaught with the unaided naked eye in daylight! - 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
