New Asterism in Canes Venatici

New Asterism in Canes Venatici was created by flt158
Hello everyone.
I was out observing on Tuesday night 28th April 2020 with my William Optics 158 mm F/7 apochromatic refractor for about 2 hours. There was plenty of slow moving cloud about. The temperature was a cold 5 degrees Celsius as I tried to do some observing in Canes Venatici. North is nearly straight up with my scope. East is to the right. I do have mirror diagonals.

It was when I was preparing a map from Guide 9.1 DVD I noticed an asterism 5 degrees west of Cor Caroli (Alpha Canum). The asterism appears to contain 8 stars and it does have a very wide true double called HJL 1070 which can be found on www.stelledoppie.it . It has magnitudes: A = 8.1. B = 8.24. Sep = 240.2". PA = 79 degrees. There is one orange star at the top of the asterism which is of 9.3 magnitude. Below that star there are 2 more stars. The one on the left is 9.8 in magnitude. The one on the right is 7.3. The next row of 3 stars have magnitudes 9.1, 8.1 and 8.2. The bottom 4th row has 2 faint stars. 9.3 mag is the one the left; 8.7 on the right. That's 4 rows in all.
Now the fun part. As I look at this whole asterism I am trying to figure out what it looks like. The 3rd row reminds me the 3 belt stars of Orion except on a miniaturized scale. But the last row of 2 stars make me think of an individual walking. So could it be a lady server in the cinema selling ice cream on a tray. I knows this takes us back to the 1960's or 1970's. But does that matter?
Perhaps some of you can provide a better description. Maybe this asterism already has a name. I don't know. Why not give it a try and see what you come up with? I will be pleased with any suggestions.

Clear skies,

Aubrey.

Hi Aubrey

There is no register of asterisms, so it is difficult to check if a pattern has been seen before.  I found it on Stellarium, the five inner stars look like they are sitting in a copy of the Keystone asterism of Hercules.  Give it a name and see how it goes.

I have mentioned on Cloudynights about the asterism I saw the other night in Hydra that looks like a question mark.  Put it up on Cloudynights and see if there is a response.

It is an open star cluster, Paul.
It's called Upgren 1.
The lads on www.cloudynights.com have cleared up the mystery.

No one has noticed my description of a cinema girl selling ice cream as yet.

By the way, I know of another question mark asterism in Cetus.
It's the only one I have seen.
It ascends from Nu Ceti.

Clear skies,

Aubrey.

Hi Aubrey, 

I very much enjoyed reading your report on Upgren 1. Your description of the cinema lady serving icecream is brilliant, and I cannot wait to take a look at her for myself. 

Very many thanks Aubrey, 

Darren.
