The Sun, in its annual motion along the ecliptic, all moment of solstizio summery (the 21-22 june) comes to find itself to its maximum declination.
Equatorial coordinates of the Sun:
d= 23°, 5 (declination)
a=90° (right ascension).

Therefore today it is the longer day of the year, and even if off topic, I have wish to celebrate it with this post. Magical date the 21 june, considered sacred in the preChristian traditions celebrated with thrilling Indo-European and celtici rituals the powers of the light and the fire, waters and the fecund earth of grass, puttinges and flowers. And also today these rituals have been renewed to Stonehenge, celebre the preistorico monument in England, where druidi and celebrating several they have celebrated the birth of the sun.   Thus, without rhetorical of demagogy, but with desire and the aspiration to “a more human” world “I allow myself to hope” that this dawn has intentional healthy a minimum of change.
To dream is lawful!

It marks it near:
