Kometa zjasnieva.Vcera rano mala 10,8 no kedze mala velkost 2min. a dc3 bola nie jednoduchym objektom na 15 cm newton.Ked ju budete hladat dalekohladom pod 20Cm tak na mieste kde ma byt
ju mierne rozostrite a viac vam vynikne.

161P/2004 V2 ( Hartley-IRAS )
It was 14 mag on May 12 when appearing in the morning low sky (Michael Mattiazzo). Then it has been brightening as expected, and it was 11.3 mag in mid June around the perihelion passage (June 16, Juan Jose Gonzalez). In its last appearance, the comet unexpectedly brightened after the perihelion passage, and reached to the maximum brightness about 45 days after the perihelion passage. In this return, it continues brightening even after the perihelion passage, too. Now it is 10.2 mag (July 2, Juan Jose Gonzalez). The diameter was small as 1.5 arcmin in mid June, however, it became much larger rapidly in early July. Now it is so large as 5 arcmin. It will be 9 mag as expected from July to August. In the Northern Hemisphere, it keeps observable for a long time after this. Now it is observable all night, however, the altitude in the morning will be lower than 15 degree in early August. In the Southern Hemisphere, it is not observable until it becomes faint.
