So tell me something. If in Brisbane Sirius does come into conjunction with the sun then how is it that you can see it at night, every night of the year? The whole point of it's being absent is because it is obscured by Sunlight. The date of it's obsuration would be the same everywhere right?

Please do your best to explain this. I know it is hard. Have patience with me.

I understand what you were saying about the days. Let me try to grasp the issue at hand.

Godbless,
Anwar

The important thing to understand is that the visibility of stars has
to do with the latitude one is at on the Earth's surface. This
affects two things:

1. The absolute visibility of any particular star. For example in
Brisbane we do not see Polaris (the pole star) which everyone in the
northern hemisphere can theoretically see (those nearer the equator
will struggle to see it on the horizon).

2. The length of daylight hours. I tried to explain how the setting
with the sun in Mecca will not be the same where you live in
Philadelphia because the sun sets later at your lattitude. The sun
does not set at the same time all over the earth.

Going over my previous posts may help with the detail but I have
researched it enough to come to the conclusions above.


The reason Sirius is seen here all year is that even when it sets
with the sun at sunset, the length of the night (as it is winter)
means that it rises before the sun does in the morning and hence is
seen at some part of the night all year round.


Peace.
