Hatfield Images of Comet 1996 B2 Hyakutake





Observer: Bob Hatfield
Location: Albuquerque & Santa Fe, New Mexico
Date: March 22, 1996 06:44 UT - 07:47 UT

I observed the comet last night from a dark site near Santa Fe and it was spectacular. I estimate the comet has more than doubled in size in both the coma and the tail visually since I observed on Monday night. The tail is naked eye easily 15 degrees and with binoculars about 20 to 25 degrees. The nuclues has had an aspect change it is no longer round but very elongated. I took some images of the nucleus of the comet (My small chip st5 has no hope of capturing the enormous tail, although I took some conventional pictures, if they are any good I'll digitize them and send them along).

Here are the technical specs on the images. All were taken with st5 ccd at -30C through C11 f6.3 telescope on 3-22-96, all have been flat fielded.

First image was taken at 06:44UTC it is a 10 second exposure.
Second image was taken at 06:46UTC it is 24 x 10 sec=240 sec exp.
Third image was taken at 07:47UTC it is a 1 second exp processed in false color.
Fourth image was taken at 07:19UTC it is 4 x 10 sec= 40 sec exp. processed in blue color.
