Andromeda's tenuous veil: A likely Milky Way nebula projected toward M31

A. Lumbreras-Calle, J. A. Fernández-Ontiveros, R. Infante-Sainz +10

A large, faint nebula was unexpectedly discovered near M31 using narrowband [O III] images. Its apparent size and the lack of a clear counterpart at other wavelengths make it uniqu…
