| Abstract: | A new series of ultra-deep, wide-angle H filter photographs at higher angular resolution than hitherto achieved, have been obtained covering the Orion-Taurus-Eridanus region. These reveal new, both diffuse and filamentary nebulosities near the Barnard Arc Nebula, which are correlated with Hi features in the region. Mechanisms capable of producing the observed features are discussed. Both a stellar wind bubble and a fossil supernova remnant are considered possible explanations, and would represent the nearest examples of these features to the Sun. Furthermore, nebulosity in this region has been photographed for the first time at Nii]. The possible implications of this and other observations are discussed. |
