WX CrA chart

(vsnet 676)

G'day all VSNET readers,

For those of you who don't have the VSS,RASNZ charts (380/381) for WX CrA, here's a *rough*(!) ASCII sketch of the starfield:

Stars m,s,p,q actually define a nearly straight line on the sky. The faint Mira GU CrA is 1.8'N of star d.

J2000 coordinates of these VSS,RASNZ comparison stars are:

d = GSC7404.03146  18h09m01.4s -37d25'27"
f =    7403.05120     08m24.5s     23'31"
h =    7403.06270     08m16.0s     17'56"
l =    7403.03829     08m17.8s     16'03"
m =    7403.04054     08m52.94s    16'32.6"
n =    7403.00399     08m57.8s     19'24"
p =    7403.00074     08m46.44s    17'01.8"
q =    7403.00349     08m43.42s    17'17.6"
r =    7403.00055     08m43.44s    16'33.5"
s =    7403.00289     08m49.37s    16'41.4"

WX CrA coordinates are 18h08m50.6s -37d19'46". GSC mags range from 10 to 13 but are unreliable.
