Suryasthamanam - the Sun set

                                          கீதாச்சார்யன் ஸ்ரீபார்த்தசாரதியின் உறைவிடமாம் திருவல்லிக்கேணியில் ஒவ்வொரு நொடியுமே விசேஷம்தான்.   இதோ இங்கே அந்தி நேரத்தில் - செவ்வானத்தில் சூரியன் அஸ்தமிக்கும் நேரம். 



பொன்னிறத்தில் தகதகக்க கதிரவன், திருக்கோவில் விமானம், கருடாழ்வார் பின்புலத்தில் கொஞ்சம் கொஞ்சமாக இறங்கி மறையும் அற்புத நிகழ்வு.  

According to Almanac @ 18:23 today is the Sunset.  Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the Spring and Autumn equinox.   

The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.  

Sunset is distinct from twilight, which is the illumination of the lower atmosphere when the Sun is not directly visible because it is below the horizon. Twilight is produced by sunlight scattering in the upper atmosphere, illuminating the lower atmosphere so that Earth's surface is neither completely lit nor completely dark. The word twilight is also used to denote the periods of time when this illumination occurs.
