New images of comet Hyakutake (1996 B2)

Mosaic image of comet Hyakutake was taken in the light of singly-ionized water moleculas on 1996 Apr. 14. The plasma tail activity continues to be high. Several streamers extends from the head region and tail bifurcation is present at the nucleus distance of 2.0 deg. Conspicious cloud of detached plasma is present at the nucleus distance of 27'.

First image: wide-field mosaic image of comet Hyakutake, taken on 1996 Apr. 14, with the 2.8/180mm lens, CCD and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). Two consecutive frames were taken between 19:03 and 19:20UT. Each frame was exposed for 5 minutes. The frame field of view is 6.6x2.4 deg.

Second image: B-W negative of the previous image.

Third image: B-W negative of the comet initial 4 deg with details in inner gas tail. A fresh cloud of plasma has been detached just few hours before this image was taken. Frame obtained with the 2.8/180mm lens, CCD and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). Exposure time was 5 minutes, starting at 19:03:50UT.
