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 ------------------------------------------------------------------------- The night started out reasonable but not perfect. Around the time of the Iridium 74 flare (mag. -0.5), cirrus came in however and I stopped observing. I followed 07-027B (NOSS 3-4r) over quite a part of its trajectory, seeing it oscilate in brightness. The series of 5 photographs with ~1 min intervals I took shows the varying brightness well, it appearing bright on some, faint on others, off-and-on. In the daytime I checked out a site in the polder at 25 minutes biking distance, which could become a future secondary observing site. It has clear view on to the horizon full around, and no street illumination for 1 km around. I still have to check it out though at nighttime. - 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
