Observer: Bob Hatfield
Location: Albuquerque & Santa Fe, New Mexico
Date: March 18-19, 1996 UT

The first image was taken from my backyard in Albuquerque on 3-18 at 07:36UTC. It is a 10 sec exp through 800mm f10 lens with st5 ccd at -30C. It is interesting only becaus of meteor or perhaps cosmic ray streak on ccd.

The rest of the images were obtained at a dark site near Santa Fe at about 8500 feet on 3-19. The st5 was at -38C for all exposures, and all have been flat fielded.

The second image was taken through 800mm lens at 07:36UTC IT is 15 x 40 sec=600sec. exp. tracked and accumulated on the nucleus. The image shows the tail from about 11 to 12 o'clock position, and either an outburst or secondary tail at the 2 o'clock position.

The third image is a false color version of hatf017 and shows the feature at 2 o'clock as a bump anywhere the color changes. The fourth image was taken through c11 f6.3 telescope at 08:39UTC. IT is 12 x 30=360sec exp.

The fifth image is a blue false color image also taken through c11 at 09:06UTC. It is a one second exp. The image scale is the same as the fourth image. The file is small because the image is cropped. The blue color enhances several uneven areas around the comet. There also appears to be an arc of material at 3 o'clock. These features may or may not be artifacts of the imaging.
