Eridanus Arc

[Jimi Lowrey]

Last fall Steve G and Big Jim C and I tried for this Arc in Eridanus. I might Add with no luck! last week the Hubble released a image of the arc. What a view.

So... how many members of the cluster were seen?

Paul.
I only got a pop once or twice of the brightest CD galaxy. But I am going to keep at it!!

I have been attempting to view gravitational arcs for over ten years, and this arc in Eridanus appeared in the literature in 2011. At the time it was the brightest apparent arc on the POSS of any I had seen. Brighter than those in Abell 1689, 2218 and 370. Even brighter than 2667, whose arc I did see in 2008. It is a perfect semicirlce on the POSS and I was excited to try it. After all that, I tried seeing this from my home in Minnesota at an elevation of about 30 degrees four times for up to an hour and had not a hint of it in my 32" under good to very good conditions. Odd that it would be so bright on the POSS and be invisible.
