Hi,
Well I finally got around to checking all this out. To the best of my knowledge, here’s what you can/can’t see from Minas Tirith in April 16 IV and why.
As to the latitudes, here is what I recently found with Letter #294:
*****
If Hobbiton and Rivendell are taken (as intended) to be about the latitude of Oxford, then Minas Tirith, 600 miles south, is at about the latitude of Florence. The Mouths of Anduin and the ancient city of Perlargir are at about the latitude of ancient Troy.
*****
Tolkien used the almanac data of 1946-47 for 3018-19 III, so Fourth Age 16 would be equivalent to 1965, if I figured things right, with 3021 the last year of the Third Age.
Venus is in conjunction with the sun (that is, in line with the sun in our sky) in April of that year and so would not be visible at ay time of day or night around April 20th. Sorry, but that’s astronomy.
From Minas Tirith looking west, you are looking back along the Ered Nimrais, a pretty lofty range that runs almost east-west near MT. You wouldn’t likely see anything low in the sky in that direction.
If you could change it to April 20 of 15 IV (1964) Venus/Eärendil would be visible from shortly after sunset (beginning to be visible shortly after 7 pm) until it drops below the horizon at about 10:45 pm. It would be about half-way between the horizon and the overhead point at sunset and would get lower as the night progresses. It would be visible above the western horizon, and might be visible over the nearest spurs of the mountains to the west-southwest for a short while after sunset.
Now a morning sighting would also be limited by mountains, the Ephel Duath, though they are further away, still it likely would not be visible until near sunrise – which would occur about 5:30 am for that date and location.
As Ithilwen noted, from the mid-nothern latitudes we don’t see Venus in the middle of the night – but due to Venus’ distance from the sun, its orbit is almost large enough to make it possible. Just experimenting with my program, set for Minas Tirith (Florence), the latest set times I saw were around 10:45 pm and the earliest rise times around 2:00 am, but the mountains near MT would prevent anyone there from seeing it unless it was well up in the sky.
You could use literary license and just MAKE it visible around 7:15 - 8 :30 pm – or – around maybe as early as 4:00 – 5:30 am and only the folks who read this thread would know that the visibility wouldn’t work according to Tolkien’s timeframe. ;) I don’t think you could stretch the times much more than that due to the mountains.
Hope that helps,
Ithildin *(
