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 Got a nice batch of points on Lacrosse 5 obtained during two passes. An attempt to capture a pass of Lacrosse 2 as well failed due to localized fields of cirrus. Conditions were poor: haze (thin cirrus) with moonlight and thicker patches of cirrus. Nevertheless got some good trails on the images: dropped two out of 8 points (= one out of 4 images in total) as that trail was so marginal that it was unmeasurable. Lacrosse 5 appeared brighter on the 2nd pass than it did on the 1st pass (mag. +1.5 on the 2nd pass, while +2.0 to +2.5 on the 1st pass). During the 2nd pass it did not do any disappearance tricks untill eclips entry, during the first it disappeared twice: shortly around 19:08:25 (maybe due to streak of clouds), and finally at 19:09:41 +/- 3s UTC (the disappearance trick like the previous two nights it seems happens at illumination phase 65%). - Marco :-) ----- Dr Marco Langbroek - SatTrackCam Leiden, Cospar 4353 Leiden, the Netherlands. 52.15412 N, 4.49081 E (WS84), +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
