The professional astronom Alan Hale and the amateur Tomass Bopp at the same time discovered a bright comet (the size of 10th stars). It hoppend at night on 23rd July, 1995. At the moment ofdiscovery the comet of Hale- Bopp was situed 7,16 ua far from the Sun. Nobody could discover such comet with an amateur teleskope, it was too far ( behind the orbit of Jupiter). The comet of Hale- Bopp in August, 1995 was 250 times brighter than the comet of Halley. But the distance from the Sun was the same. The first analysis of   results could inform thatthe maximum of the brighteness of the comet would be anticipate in March- April, 1997. the comet of Hale- Bopp reached its maximum brightness when it was situated in the North hemisphere. At that moment it was seen in Latvia very well, too.

            In the first photo of Hale- Bopp, wich was taken in Latvia with the Riekstukalna telescope in the evening of   10th August, 1996 (picture 1) when the comet was 3,5 ua far from the Sun and 2,7 ua far from the Earth, the photo of the comet didnít have any difference from the bright starís picture. But it was possible to see a head of the little bit assimetric. The Hale- Bopp comet was 2,4 ua far from the Sun and 3 ua far from the Earth on 14th November. The photo of the comet in the 4 minutes long exposition was about the same size as it was in the previous photo, but it had more concrete jets wich looked tike stars- looked like tails.

            During 3 month the comet had come down the Sun, it was 1,2 ua far from the Sun and 1,7 ua far from the Earth. The diameter of the head of the comet taken on 18th February, 1997 (picture 2) in the 5 minutes long exposition was about 5 mm, but the tail was about 4 cm long or 1 0 long.

            On 5th March in the 30 minutes long exposition and in the evening on 26th March (picture 3) in the 5 minutes long exposition it was possible to see its plasmatic tail. The dust tail was gushed and it was without the expressed structure to compare with the tail of gas.
