Description

Hello everybody...! Well we have to keep going, dont we? So, albeit the opacity of the sky, I could try to point to a star that always amazes me, but I never could extract too much of its colors...so I almost didnt sleep last night, and tried to got a little bit of the Star AlNiyat (well ... a multiple star system) !!! I think its fair result for 318 minutes of subs... Hope you enjoy!! :-)

From Wikipedia:

σ Scorpii (Latinised to Sigma Scorpii) is the star system's Bayer designation. The designations of the four components as Sigma Scorpii Aa1, Aa2, Ab and B derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).

Sigma Scorpii and Tau Scorpii together bore the traditional name Al Niyat (or Alniyat) derived from the Arabic النياط al-niyāţ "the arteries" and referring to their position flanking the star Antares, the scorpion's heart, with Sigma Scorpii just to the north.

In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[16] to catalogue and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. It approved the name Alniyat for the component Sigma Scorpii Aa1 on February 1, 2017 and it is now so included in the List of IAU-approved Star Names.

In Chinese, 心宿 (Xīn Xiù), meaning Heart, refers to an asterism consisting of Sigma Scorpii, Antares and Tau Scorpii.[18] Consequently, the Chinese name for Sigma Scorpii itself is 心宿一 (Xīn Xiù yī), "the First Star of Heart".

The indigenous Boorong people of northwestern Victoria in Australia saw this star and Tau Scorpii as wives of Djuit (Antares).
