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

    Questions about transits in Hong Kong

    When is the next ISS transit in Hong Kong?

    The next good transit near Hong Kong is the ISS crossing the Sun on Sat 10 Oct at 16:46:11.6 GMT+8 (08:46:11.6 UTC). Its centreline passes 153 km SW of central Hong Kong, and the strip is 30 km wide. It is 18° up in the WSW and the crossing lasts 1.48 s.

    Do I need to travel to see one from Hong Kong?

    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 153 km from central Hong Kong, so the strip's edge is 138 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.
