Where does your sun rise?

In the East... but only on the 2 days of the year that are called the Equinox: Sept 24 and March 18th. In the winter it rises further south than tre East.

Here is our sunrise. On June 14 it was to the North, over the neighbor's house at 4:30 AM. On August 22 at 7:00 AM, it was just off the tip off Spruce Cape. And on September 21st (three days before the Autumn Equinox), it is rising close to true East at 8:30 AM.

By December 21, the Winter Solstice, our sun will rise 50 degrees further to the South than it does on Sept 24...... well outside the right side of the picture.

Where it rises depends on how far north of the equator you live. We live at 58 degrees north of the equator. Denver (which is 40 degrees from the equator) will see the sun rising just 30 degrees south of East! At the equator, it will rise just 22 degrees south of true East during the winter Solstice.That's because the Earth tilts more the further north you travel and, in fact, is alot more elliptical or thin at the top and bottom than midway from the equator. So the position of the sun rising and setting changes alot more on the horizon the further north your travel.

Correction: This year the Fall Equinox is Sept 22nd, not the 24th; and the Spring Equinox is March 20th, not 18th. It was 1903 when it was on Sept 24th and it shall not be repeated on that date for 3 more centuries from 1903(near as I can tell). Just in case you realy wanted to know.

What I want to know is why you were up at 4:30 am taking pictures of a sunrise? That's dedication if I've ever seen it!!

Whenever they wake me up for a case, I can't get back to sleep. So I take pictures of sunrises or write a blog. Needless to say I don't always type correctly.

By the way,even my correction is incorrect. It will be 400 years from 1903 when the equinox will fall on Sept 24 (not 300 years) But I won't bore you by telling you whay that is.

I just happened to be flipping through the comments and saw that you replied to my comment months ago. Now that I got my answer I can die a happy gal. :)
