Neutral Gas Bubbles Surrounding Southern Optical Ring Nebulae: Anon(WR23) and RCW52

Based on interferometric H I 21 cm line data we analyze the distribution of the neutral hydrogen in the environsof the optical ring nebulae around WR23 (WC6) and LS 1887 (O8V). We identify the interstellar atomic gasbubbles associated with the optical ring nebulae Anon(WR23) and RCW52.
