Detailed Information:
This comet surprised observers by suddenly increasing in brightness and size. It eventually was larger than the moon. The tail was difficult to visualize as it was directed mainly away from earth and only slightly oblique in orientation. Careful inspection of the image reveals a slight elongation in the region of the core that represents some of the comet's tail structure.

The image was created by doing two series of combines. The first was on the comet core resulting in blurred stars. Then a second combine using the stars to align was created blurring the comet. After selectively removing the stars from the first and the comet from the second image, the two were combined to create this image.
