Over the next few days there are a series of  bright ISS passes in the early evening. The outstanding passes are when the ISS passes above the Southern Cross or the pointers, or very close to these bright stars.

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 planet or missing it completely. As always, 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.
