Here is another butchered elset Iridium 84 ? 4.0 1.8 0.0 6.0 d 7.3 724 x 721 km 1 25530U 98066D 01005.63685683 .00000400 00000-0 -55546+1 0 1485 2 25530 86.5376 340.1197 0002257 311.1302 49.0069 14.51006879116045 It must be a coincidence but the predictions from either of these elset differ only 2-3 minutes in time at 17:50 UT Jan 11.
