		| Abstract: | 
		The origin of the anomalous, hard X-rays from γ Cas is reviewed  from data obtained from several X-ray, UV, and optical campaigns. We discuss correlations between X-ray and optical or UV fluxes ranging from rapid undulations to long-term periods and optical Be outbursts. All the evidence points to the X-rays originating from volumes close to where the  UV diagnostics are formed, the Be star, and not for example from a binary companion. |
