There were two very bright naked eye comets in 1947 and 1948. The rest of the dozens of comets found between 1947 and 1952 were rather faint and in most cases not visible except with a telescope.
The Great Comet of 1947, Comet 1948l, was also called the Eclipse COmet because it was a spectacular sight during the first week of November during a total solar eclipse when it was approaching the Sun. It was, however, a Southern Hemisphere object not well seen by people in the Northern Hemisphere. See Sky and Telescope magazine, January 1949 for pictures and commentary.
The Great COmet of 1947, Comet 1947n, was first seen on December 8, 1947 and had a 25 degree long tail from locations in South Africa. It was hailed as the brightest comet since Halley's in 1910. See articles in Sky and Telescope magazine for February and March, 1948 for more details.
