[Lvas] FW: FW: Virgo Diamond

[roger ivester]

To all member of the LVAS,

 

Tom English sent me this most enlightening e-mail regarding the "Virgo Diamond". Hopefully I can send you the "image" before the weekend.

 

Enjoy...roger ivester

> I looked up the Virgo Diamond on the Sloan Digital Sky Survey and Wikisky tonight. An SDSS image is attached. This is a very neat little group.
> Go to Wikisky (http://www.wikisky.org/), zoom out from M31 (the default view), drag the view around until you find Virgo, then zoom in on the appropriate coordinate. If you move your mouse over an object it will give you information. 
> 
> The diamond is clearly seen in these interactive surveys, and the westernmost star is a double, giving 5 stars. 
> Looking for this 5th star is certainly a greater challenge than looking for extra stars in the Trapezium (but don't tell BoB!)
> 
> The northernmost star is TYC 4948-53-1 (12h33m18.96s, -0d38'32.3", m=10.892)
> The westernmost star (the double) is USNOA2 0825-07771246 (12h33m17.88s, -0d38'59.1", m= 12.1)
> The southernmost star is USNOA2 0825-07771362 (12h33m19.61s, -0d39'15.7", m=13.7)
> The easternmost star is USNOA2 0825-07771459 (12h33m20.79s, -0d38'50.5", m=13.45)

> The TYC star was measured by the Hipparcos mission, thus explining its precise magnitude measurement. I looked it up at the Hipparcos web site, and found that its parallax had been measured to be 64.8 milliarcseconds, putting it at around 50 light years from us. Here's the Simbad page for the star: http://simbad.u-strasbg.fr/simbad/sim-basic?Ident=TYC+4948-53-1
