Another good Week for ISS passes, (9 November - 16 November 2017)

The ISS passes below Saturn, as seen from Melbourne on the evening of Sunday 12 November at 22:23 AEST.

Starting Thursday there are a series of bright evening passes of the International Space Station lasting around seven days. Some are low to the horizon, some rapidly enter earth's shadow, but for many places in Australia this series has the ISS gliding either close to Saturn or a series of bright stars (except Darwin, which only gets three bright evening passes low above the horizon).
 
The ISS passes extremely close to the bright stars alpha and Beta Centauri and Fomalhaut during some of these passes (check your local predictions). The following tables are from data provided from Heavens Above.

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 a star or 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. Use the most recent prediction for your site.
