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 lucky to catch 05-016A during a clearing inbetween strong hail showers - 10 minutes later hail was pouring down. A second pass at 19:19 UTC was missed due to cloud cover. During the imaged pass, 05-016A did its "disappearance trick" again. At about 17:39:26 UTC while it sailed below Polaris, it dropped from mag. +2 to +4 in a mere few seconds, after being steady, slowly rising from +2.5 to +2.0 the minute before. I was taking my second exposure as it happened, and it is clearly visible on the image how the brightness drops quickly, see the image at: http://sattrackcam.blogspot.com/2006/11/lacrosse-5-doing-its-tricks-amidst.html The sat was too faint to be visible at the third image, but I could faintly see it with the naked eye at that time at about mag. +4 or so. - 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
