Observer: Antonio Jose Cidadao
Location: Oeiras, Portugal
Date: March 28, 1996 22:31 UT
Notes: Comet 1996B2; 16 images of 5 sec. each were averaged after an
appropriate shift in order to align the nuclear condensation.
Original images were obtained with a 135mm (f/1.8) telephoto lens
and a SBIG ST6 CCD camera, piggy-back mounted on a 10" LX200.
Images from left to right represent a linear stretch, a log
processing, and the result of subtracting a blurred log image from
the log itself. This last processing clearly shows jets originating
from the nuclear condensation. In the second picture the "tail" jet
is apparently separated from the nuclear condensation (a result of
the reported nuclear fragmentation?)
