When is the next ISS transit in Philadelphia?
The next good transit near Philadelphia is the ISS crossing the Sun on Fri 9 Oct at 16:17:06.9 GMT-4 (20:17:06.9 UTC). Its centreline passes 153 km SW of central Philadelphia, and the strip is 20 km wide. It is 24° up in the WSW and the crossing lasts 1.17 s.
Do I need to travel to see one from Philadelphia?
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 Philadelphia, so the strip's edge is 143 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.
