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 I was up early and did a morning session. Clear sky but with occasional fast moving streaks of low clouds. Targets were Lacrosse 3, Lacrosse 5 Rk and ISS. Highlight of the night was a fine pass of the ISS at 6:37 local time (5:37 UTC), see the two pictures here; http://sattrackcam.blogspot.com/2006/11/lacrosse-lacrosse-rocket-and-iss.html When it came into view at about 35 degrees altitude, close to Procyon, it already was well into the negative magnitudes, about magnitude -3 I estimate. It stayed that bright while crossing the body of Leo and passing close to Saturn at about 55 degrees altitude: it dimmed when going towards the eastern horizon. It had a somewhat orange colour again. I have seen ISS this bright before, but that was during zenith passes. I wonder what brightness it currently could attain in the zenith. Hope to be able to check that out soon, as ISS starts to make more favourable morning passes. The Lacrosse 5 Rk rocket stage (05-016B) made a nice pass too. While traversing from Auriga into Gemini around 4:57 UTC it was quite bright, magnitude +1. Once in Leo at 4:58 local time, it had faded to mag +3.5. Got 2 photographs and hence 4 positions, but the last one I dropped because it came out clearly erratic. My first target Lacrosse 3 (97-064A) around 4:17 UTC was faint, the trail on the photograph was rather marginal. My results suggest it was 0.1 degree off-track relative to a 5-day old elset, but as the trail was very marginal, don't pin me down on it. ISS positions are for fun and calibration check. - 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
