See the historical views of comet Hyakutake, passing near the Polaris in early morning of Mar. 27th. These images were taken by Herman Mikuz and Bojan Kambic from a dark site at Slovenske Gorice, 170km east of Slovene capital Ljubljana. On otherwise cloudy Central Europe, the weather satellite shows a small gap approaching to NE Slovenia. We traveled to this distant site and indeed enjoyed a 3-hr clear period. We were both impressed due to the splendid Hyakutake display. With the naked eye the tail spanned for 45 deg, up to Beta CVn and the estimated comet m1 was 0.4 magnitude. All images were guided on comet nuclear condensation. |

Wide-field view of comet Hyakutake passage near the Alpha UMi was taken on 1996 Mar. 27 (1h03-1h25UT) with the 3.5/65mm lens and T-Max 400 film (6x6 format).
The field size is ~40x35 deg. The tail length is about 30 deg. The constellation of Ursa Major is visible on the upper part of picture.

| March 20-21 1996 | |
| Series of images were taken on the night of 1996 Mar. 20-21 from the Crni Vrh Observatory in very good conditions. Of special interest are mosaic images displaying the complex ion tail structure with rays, knots and clouds of singly ionized water moleculas. The ion tail total length on 65mm f.l. images is about 20 degrees. Additional monitoring with red continuum filter shows only featureless ~7 deg broad tail. | |
