The ISS Crosses the Moon in Brisbane (21 November 2015)

As noted previously, on the evening of Saturday 21 November, parts of Brisbane south of the river will see the International Space Station pass in front of the Moon (the rest of Brisbane will see it coming very close).

Path of the centre line of the ISS passing in front of the Moon, there is a narrow band around the centre line that will also see the ISS pass in front or the Moon (click to embiggen). (this link may update properly, or not)

The current path of the ISS puts it on a line running through Forest Lake, Dollandella, Acaia Ridge, Toohey Forest Conservation Park, Whites Hill Reserve, Carina Heights, Tingalpa, Wynnum and Elanora Park.

However, the path of the ISS is still evolving, and the centre line may change further before Saturday. Use your exact location (or choose a location close to the centre line as defined above) in either CalSky or Heavens Above (both have drag and drop maps if you don't know your exact longitude, but it may take a while to navigate the layers) to see if the pass occurs where you are, or if you have to hike a bit to see it.

The ISS will be moving fast, and will cross the face of the Moon in under half a second.

You will need to be set up well before hand.

If you want to capture the pass, you should have a camera with a tripod and should use your cameras video feature (or rapid burst mode where a number of shots are taken in quick succession).

Keep checking the timing on the evening of the pass, and be prepared for the published timing to be slightly out (that's why you should set up early and be prepared to video or take multi-shots in burst mode at times that bracket the nominal pass time). A watch or clock with sub second accuracy is a bonus.

Comments:

Such phenomenon does not occur regularly and to be able to witness such a rare occurrence is definitely a once-in-a-lifetime experience not to be missed. I was dropping some stuff off at a self storage in Brisbane and I remembered a friend telling me of this theory but we did not manage to catch any rare sighting in the sky at that moment of time.
