Comet Morehouse
Comet Morehouse was a bright, non-periodic comet discovered by US astronomer Daniel Walter Morehouse on September 1, 1908, at Yerkes Observatory in Williams Bay, Wisconsin. Morehouse was a graduate student at the time. It was unusual in the rapid variations seen in the structure of its tail. At times, the tail seemed to split into up to six separate tails; at others, the tail appeared completely detached from the head of the comet. The tail was further unusual in that it formed while the comet was still 2 AU away from the Sun, and that there was a high concentration of the CO+ ion in its spectrum.
