Since the elset that I reported in an earlier message, IRIDIUM 84 1 25530U 98066D 01005.63685683 -.18147655 00000-0 -55546+1 0 1485 2 25530 86.5376 340.1197 0002257 311.1302 49.0069 14.51006879116045 no more recent TLEs for Iridium 84 have appeared. Does this mean that OIG have "lost" it? This actually raises the question of how OIG identifies objects that have had a major orbital adjustment. Presumably, the disappearance of an object from its predicted position combined with the appearance of an unknown object will prompt an attempt to match old with new. On the assumption that Iridium 84 is being raised to fill the gap left by the removal of Iridium 9, it might be worth anyone with good sightings of Iridium orbital plane 5 to look out for it (or for flares from it). It should be midway between Iridium 53 and Iridium 10. An old elset for Iridium 9 from before is was lowered last September should give a good guide to where to look, maybe accurate to within a few seconds. -- Rod Sladen, Beeston, Nottinghamshire, UK, 52.923N, 1.219W ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
