This is for all those "the sun is too far south" people...
This is how you can check to see "if" the Sun is indeed in the correct place in the sky "or not"...
1] Use Google Earth to find your location and zoom in so that the area being viewed is around 20mi x 20mi or less. Preferably zoom right in to your location and mark your viewing position (you can use Google Earth's Placemarker function to do so) and then zoom out.

2] Save the image [ensuring that the map is aligned precisely with north (on top) before doing so.]
3] Get the exact Sunrise and Sunset positions (and you can also verify the exact times) for your location for the day or days you wish to verify:

Look for Sunrise Azimuth and Sunset Azimuth. Make a note of these two angles.
4] Use a graphics program that can measure angles (usually displayed when drawling lines.) E.g: CorelDraw, Illustrator, etc. (There are many others that will do the trick, including Shareware and Freeware programs that are be easily downloaded and installed.)
Paint Shop Pro will work nicely for this:

5] Now load the image in to your graphics app of choice, draw two lines, each from your location out to the angles (sunrise azimuth and then sunset azimuth) where 0 degrees is north (top of your image) and 180 south, going clockwise.
6] You can now check to see 'just where' (and when) the Sun does in fact rise and set and compare it with the lines you have just drawn on your Google Earth image. You should be able to identify landmarks, trees, buildings, etc.
