See the ISS buzz Jupiter and Mars AGAIN (22-23 July, 2016)

On July 22 and 23 there is series of bright passes of the International Space Station occurring in the early evening. In some places in Australia the ISS will pass close to Mars and Antaresat varying times, others close to Jupiter and in still others there are close passes to bright stars such as the pointers, sometimes close passes to all of the above and in a few places the ISS might even pass over Jupiter or Antares.
Friday evening (22 July) sees the ISS pass close to Antares and Saturn as seen from Perth and Adelaide. Sydney, Alice Springs, Brisbane and Melbourne all see close passes to Jupiter, with Sydney almost seeing the ISS pass in front of it (regions nearby may see the ISS pass over Jupiter).
Saturday evening (23rd) Sees the ISS pass cose to Antareas and Saturn from Alcie SPrings (with the ISS almost passing over Antares) and Brisbane, With Adelaide, Sydney and Perth seeing reasonably close passes to Jupiter.
On both dates there are also closish passes to various other right stars (like the pointers and Arcturus).
When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over Jupiter and missing it completely.
Start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions.
