Not found in the original Bayer catalogue, it was given the Bayer-like designation Upsilon1 Ceti by Flamsteed[5] to distinguish it from Bayer's Upsilon Ceti (which Flamsteed designated Upsilon2 or 59 Ceti). Bode included this designation in his Uranographia,{{citation needed|date=February 2017}} but the superscripted designations Upsilon1 and Upsilon2 are not in general use today. 56 Ceti is also known as HD 11930.
