XMM OBSERVATIONS OF THE UNIDENTIFIED comma VARIABLE comma COMPTEL GAMMA-RAY SOURCE

We request observing time towards the recently discovered unidentified, variableCOMPTEL gammaray source. There are three ROSAT sources already detected in thisregion, but only with 8 photons each, such that spectral analysis of them hasnot been yet possible. This observation will allow to obtain their spectrum,distinguish between their diffuse or pointlike character, and analyze theirtemporal behavior. This observation will also allow to search for Xraycounterparts of five radio sources detected nearby and uncover any other Xrayemitter lying in the field of view of the EPIC cameras which would be plausiblyrelated with the COMPTEL detection. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
