Williamina Fleming discovered IC 430 = HN 65 on a Harvard College Observatory photographic plate taken on 27 Jun 1888. She noted a "nebulous band 3' wide extending 10' north preceding from DM -7° 1142." Edward Pickering published the discovery in the 1890 Harvard Annals publication (1890AnHar..18..113P)."
400/500mm - 18" (1/21/04): very faint, fairly large low surface brightness glow to the northwest of mag 4.8 49 Orionis, ~4'. Extends to a wide pair of mag 13 stars. This reflection nebula needs to be reconfirmed as the bright star may have confused the observation. See IC 429, which lies at the northwest tip of IC 430.
