Note on the Transit of the Shadow of Titan over Saturn, 1877–78

This is not a pulp magazine cover. The image is a page from a 19th-century astronomical journal — specifically observational notes by Lord Lindsay and Dr. R. Copeland recording the transit of Titan's shadow across Saturn on Christmas Day, 1877, made with a 15-inch refractor at Dunecht Observatory. Columns of Greenwich Mean Times log whether the shadow was 'up,' 'barely up,' or 'past,' culminating in a calculated central passage of 5h 54m.3. Published in Monthly Notices of the Royal Astronomical Society, Vol. XXXVIII, it belongs to the history of planetary science, not pulp fiction. No cover art, no genre typography, no painted illustration is present.
