9 of these are hidden on the main finder by its quality filter (too low, a barely lit Moon, or a weak crossing). Times are Sydney time to a tenth of a second; distances are to the centreline of the strip from central Sydney.

    Questions about transits in Sydney

    When is the next ISS transit in Sydney?

    The next good transit near Sydney is the Envisat crossing the Sun on Sun 11 Oct at 15:56:49.7 GMT+11 (04:56:49.7 UTC). Its centreline passes 118 km E of central Sydney, and the strip is 16 km wide. It is 37° up in the WNW and the crossing lasts 1.61 s.

    Do I need to travel to see one from Sydney?

    Usually a short way. The strip where a transit is visible is only a few to around 20 km wide, so it rarely crosses your own street. The next good one passes 118 km from central Sydney, so the strip's edge is 110 km away.

    Can I see a transit without a telescope?

    The crossing lasts about a second and the station appears tiny, so a telescope or a long lens on a camera is needed to see its shape. Never look at the Sun without a certified ISO 12312-2 solar filter.
