A good week for ISS passes (close to Orion and the Moon. 20-25 February, 2018)

Over the next few days there are a series of  very bright ISS pass, some in the morning where the IS passes close to Antares and the bright planets Jupiter and Mars and some in the evening where the ISS passes through or above Orion, in some locations the pass is close to the crescent Moon. There is a particularly close pass near Perth, and in some locations the ISS may pass over the Moon.

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 the Moon (or the stars in Orion's Belt) 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.
