47P/Ashbrook–Jackson is a Jupiter-family comet with an 8.35-year orbit around the Sun. It is the only comet discovered by Joseph Ashbrook and the third and final one by Cyril V. Jackson.
== Observational history == The comet was first spotted by Joseph Ashbrook while examining a photographic plate exposed from the Lowell Observatory while observing the asteroid 1327 Namaqua on the night of 26 August 1948. At the time it was a diffuse, 12th-magnitude object with a tail about a degree in length, located within the constellation Aquarius. It was independently discovered by Cyril V. Jackson from the Yale-Columbia station at Johannesburg just a few hours later.
