****************************************************** PR # 31244 We propose to two compact galaxy groups HCG48, HCG42 that were omitte d at AO-1. HCG62 observation of adopted our proposal detected diffuse X-ray emission as ROSAT. The best fit value of Raymond-Smith is temp erature of 0.85 keV and abundance of 0.17 solar. But, we discovered s trong Argon line emission for best fit model. It is possible to low a bundance because of other reason. Heavy elements will be disappears i n dust and only Argon of rare gases can be seen in diffuse hot gas. A rgon line emission rate was unclear in HCG62 observation. We should o bserve new bright same galaxy groups that is secured positive eviden ce. So we propose this target that be expected with strong diffuse em ission. ******************************************************
