Iridium Flares, Saturday 8 April

This image shows the path of the ISS satellite on Saturday April 8 as seen from Adelaide (facing north-north-east). In Hobart the satellite passes closer to the Moon, in Melbourne, Perth and Brisbane closer to alpha Leo, but otherwise the views are much the same. (click to enlarge).
While waiting to see Callisto, people in Adelaide, Hobart, Melbourne, Brisbane and Perth (Sydney misses out for some reason) will see a nice bright Iridium Flare (magnitudes -7, -6, -2, 0 and -8 respectively, for comparison, Venus is magnitude -4.6 at the moment and Jupiter -2.4). The satellite track is shown in the picture. The Flare maximum brightness is at 19:34 in Adelaide, 19:25 in Hobart, 19:36 in Melbourne and Perth and 19:12 in Brisbane. In all cases the flare should appear in roughly the middle of Sextans, just above Leo. If you want to check your own location, see my flare section at Southern Skywatch.
