The newly discovered tail of neutral sodium atoms (see IAUC 6631 and Web pages made by the Isaac Newton Group, Canary Islands) is a major new feature, never seen in bright comets in the past, excepted during some hours in the sungrazing ones, but under very extreme temperature conditions that comet Hale-Bopp does not experience. We used a 50-mm F/1.4 Pentax photographic objective , a narrow band interference filter and a HiSiS-44 CCD camera (equipped with a Kodak 1536x1024 chip) to observe the new sodium tail of the comet. The field of view was not less than 15x10 degrees. The bandpass centered on the yellow D line doublet was 2.8 nm wide. The present image is a 32 minutes integration. North is up. The sodium tail is the narrow 8 degrees long feature near p.a. 55 degrees. Do not confuse it with the ion tail, of which general orientation is roughly similar : in fact no ion emission seems exist in our filter bandpass.
