Comet Morehouse (modern formal designation: C/1908 R1) was a bright, non-periodic comet discovered by US astronomer Daniel Walter Morehouse and first observed on September 1, 1908 (the discovery photograph was taken on September 1, but the comet was not noticed until the following day), at Yerkes Observatory in Williams Bay, Wisconsin. Morehouse was a graduate student at the time.[2][3] It was unusual in the rapid variations seen in the structure of its tail.[4][5] At times, the tail seemed to split into up to six separate tails;[citation needed] at others, the tail appeared completely detached from the head of the comet.[6] The tail was further unusual in that it formed while the comet was still 2 AU away from the Sun[6] (where distances of 1.5 AU are more usual)[citation needed], and that there was a high concentration of the CO+ ion in its spectrum.[7]

As is typical for comets fresh from the Oort Cloud, its orbital solution is more or less parabolic;[3] if its orbit is in fact closed, it will likely not return for millions of years.
