Here I would like to report on the HI intergalactic cloud in the Leo group of galaxies, which was first announced in 1983 by Schneider, Helou, Salpeter and Terzian (1983). This unexpected discovery was made accidentally by S. Schneider while calibrating the Arecibo λ21 cm system by looking at a part of the sky where no HI emission was expected at high velocities. These observations were made during a project of studying the HI distribution in binary galaxies and in small galaxy groups.
