The answer is no, and the shape traced out by the <A href="http://antwrp.gsfc.nasa.gov/apod/ap000621.html">Sun</A> over the course of a year is called an <A href="http://www.uwm.edu/~kahl/Images/Weather/Other/analemma.html">analemma</A>. The Sun's apparent shift is caused by the <A href="http://zebu.uoregon.edu/~soper/Orbits/earthorbit.html">Earth's motion</A> around the Sun when combined with the <A href="http://www.crh.noaa.gov/fsd/astro/season.htm">tilt of the Earth's</A> rotation axis. The Sun will appear at its highest point of the <A href="http://solar-center.stanford.edu/FAQ/Qsunaspattern.html">analemma</A> during <A href="http://antwrp.gsfc.nasa.gov/apod/ap001223.html">summer</A> and at its lowest during winter. <A href="http://www.jgiesen.de/analemma/">Analemmas</A> created from different Earth <A href="http://www.cogtech.com/EXPLORER/lat-long.htm">latitudes</A> would appear at least slightly different, as well as <A href="http://www.wshs.fcps.k12.va.us/vault/svanbroc/analemma.htm">analemmas</A> created at a different time each day. The <A href="http://www.finseth.com/~fin/Java/Analemma0.html">analemma</A> <A href="http://vrum.chat.ru/Photo/Astro/analema.htm">pictured to the left</A> was built up by <A href="http://www.shadow.net/~bobt/office/office.htm">Sun photographs</A> taken from 1998 August through 1999 August from <A href="http://www.cia.gov/cia/publications/factbook/geos/up.html">Ukraine</A>. The foreground picture from the same location was taken during the early evening in 1999 July.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/F8DD2673-E821-4331-9EDB-BBD794523396/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
