As a result of a resurgence in Galactic HI astronomy, a HI Cloud with a few peculiar properties was detected (arXiv:0810.3846v1). In particular, the cloud is found to have a) a large velocity gradient b) an elliptical distribution c) filamentary structure and d) no correlation with emission in any other waveband. These properties combined suggest an interesting environment for this enigmatic HI Cloud - dark galaxy or expanding circumsteller shell??...
