Two Large H [CSC]i[/CSC] Shells in the Outer Galaxy near [ITAL][CLC]l[/CLC][/ITAL] = 279°
As part of a survey of H I λ21 cm emission in the southern Milky Way, we have detected two large shells in the interstellar neutral hydrogen near l = 279°. The center velocities are +36 and +59 km s-1, which puts the shells at kinematic distances of 7 and …
