This image had a decisive role. If it were not for this image, I would be sure that the comet had to be under horizon. I am an inhabitant of the norther hemisphere (Central Europe, Czech Republic) and I have poor knowledge of the southern sky and therefore I did not recognize that the comet was circumpolar. Fortunately a small hole in clouds enabled me to take this image and I realized that finding a suitable observing place, I would have had a chance to take good comet images before the daybreak.
