The list of stars used in the asterism is completely garbled in all of the articles - all quoted Phillippe Mollet from the observatory as giving this list of stars:
. . .we chose seven stars - Sigma Librae, Spica, Alpha Virginis, Zeta Centauri, SAA 204 132, and the Beta Sigma Octantis Trianguli Australis - in the vicinity of Mars.
Eek! That looks like a list of six stars, but . . .
(1) Alpha Virginis is another name for Spica, so two of the stars are the same star.
(2) "SAA" plus a number suggests a star catalogue, but I don't know which one.
(3) "Beta Sigma Octantis Trianguli Australis" seems to be one star, but it has to be two stars, perhaps Beta Octantis and Sigma Trianguli Australis or Sigma Octantis and Beta Trianguli Australis.
That still makes only six stars, so one is missing.
The WeatherNetwork looked carefully at the tribute diagram and suggested that they meant Spica (Alpha Virginis),
SAO 204 132, Delta Octantis & Beta Trianguli Australis, plus SAO 241 641, which wasn't listed.
Here is what they think the asterism's stars are.
