摘要：

In this letter we report on the serendipitous discovery of a giant arc in the Abell Supplementary cluster S295 during optical follow-up observations of clusters detected in the ROSAT All-Sky Survey. The cluster has a redshift of 0.30 and a velocity dispersion of sigma(upsilon) congruent-to 900 km s-1. This is the first giant arc newly found in a ROSAT Survey cluster, indicating the potential advantage of searching for giant arcs in X-ray selected clusters.
