This image of Comet C/2001 Q4 (NEAT) was taken at the WIYN 0.9-meter telescope at Kitt Peak National Observatory near Tucson, AZ, on May 7, 2004.
The image was taken with the Mosaic I camera, which has a one-square degree field of view, or about five times the size of the Moon. Even with this large field, only the cometâ€™s coma and the inner portion of its tail are visible. This color image was assembled by combining images taken through blue, green and red filters.
A small star cluster (C0736-105, or Melotte 72) is visible in the lower right of the image, between the head of the comet and the bright red star in the lower-right corner.
Comet C/2001 Q4 (NEAT) was discovered on August 24, 2001, by the Near Earth Asteroid Tracking (NEAT) system operated by NASA™s Jet Propulsion Laboratory, Pasadena, CA.
The comet will remain visible for several weeks with binoculars and small telescopes just after sunset, high in the western sky.
