Hi all,

I bring my piece of info concerning asterisms. We published a couple of
articles about these cluster-like objects in back issues of Ciel Extreme,
our deep sky dedicated publication here in France
(http://www.astrosurf.com/skylink/publi/cielextreme), and here is a
gathering of the asterisms we have found.

ANR means "amas non repertories" ie "uncatalogued clusters".
The number following ANR is a composite of both coordinates.
RA and DEC are to be found next.
D is the diameter/size of the object in arc minutes.
MA is the minimum aperture the asterism was seen (not always the real
minimum, you have to rely on the magnitude estimates of the stars).
C is the confimation of other observers; no C means the asterism has not
been confirmed and "C=3Dx" means the object has been seen by another observe=

If you happen to cross one of these asterisms, do not hesitate to contact
me. More confirmations are always welcome.

BTW, I have found another one near M73 (already an asterism) this summer. I
had located M73 and got prepared for drawing it and back at the eyepiece,
my unmotorized dob hadn't followed M73 and I had to move back and by doing
so I found a small clustering that looked very much like M73. I started
drawing it but moving back to M72, I got back to the real M73... Here are
the coordinates: 20h55m, -13=B010'. Check for yourself.

The Golden Horseshoe could be ANR 1450-6612 or UC1450-6612 if you prefer;
and the mini Orion would be UC 0726-2305;
clear skies, Yann.
