[195.02] A Gigantic Eruption from the Inner Disk of the Milky Way

We have discovered a coherent structure, which seems to be a huge superbubble reaching higher than 3 kpc from the Galactic plane. It has been detected in both H\alpha and HI and a detailed HI map of it has been produced with the Green Bank Telescope. The total hydrogen mass within the outflow is \approx 106 M\odot and its energy content is of order 1053 ergs. At the top of the structure there is a peculiar ``plume'' consisting of more than 104 M\odot of hydrogen.

The NRAO is operated for the National Science Foundation by Associated Universities, Inc., under a cooperative agreement.
