I use 'Your sky' to find out how the sky looks from Easter Island in the middle of the night at winter solstice, and these are the input values to the program:
By showing stars with magnitude greater than 4.0 we will be able to discern the Milky Way:
Antares (Ana-mua) at left (16h 26) seems to be the station at the beginning of the 'Snake-river' stretching towards Rigel and Betelgeuze (Ana-varu) at right. If we change the observation times from midnight to early morning (06.00) the view will be:
At dawn Antares has moved to the center of the sky, while at dusk (18.00) Antares will no longer be visible:
It disappears at the western horizon around noon (when of course it cannot be visible because of the light from the sun). West is at right in the pictures, as if viewing southwards from the north. Turning around to look at the sky from the south the picture must be reversed with E at right and W at left. The area closest to the south pole has no prominent stars. Attention instead is drawn to the Southern Cross (Crux). It is located just below the center in the picture below:
"... Whittier said, in his Cry of a Lost Soul: The Cross of pardon lights the tropic skies; which is correct for our day, as it is not now entirely visible above 27º 30' of north latitude. It was last seen on the horizon of Jerusalem - 31º 46' 45'' - about the time that Christ was crucified. But 3000 years previously all its stars were 7º above the horizon of the savages along the shores of the Baltic Sea, in latitude 52º 30' ..." (Allen) |
