Possible gravitational lens arc?

The modelling says the blue wisp to the left of this cluster is an edge-on disk, but it looks like a possible gravitational lensing arc too. Does anyone know if this cluster has been imaged by Hubble?

I wasn’t expecting to have to undertake a MASTers degree before being able to find out!

…Actually it wasn’t too hard to load up the coordinates, but I couldn’t tell if it had loaded the same view as I couldn’t identify any of the star formations! No HST images though.
