Comet with naked eye coma Wirtanen - 26.12.2018 at 17.50 - 26.12.2018 at 18.40 Kirkkonummi Observation number 79905

Visibility III / V

Jouko Markkanen, Ursa (Helsinki)

Finally, the sky became clear even in the metropolitan area, so that you could wonder about Wirta. I classify the observation as a binocular comet, although yes, that spot on the naked eye just stood out when appropriately looked aside. The pictures already have a clear greenish glow.

The first image is 100mm f / 2.8, the light is about 23 minutes in total (30 sec in chunks), the second image is taken from one 24mm shot with light pollution removed from the north sky.

Jos se kerran näkyi paljain silminkin, niin muutan otsikkoa, jotta saadaan käsitys paljain silmin -havaintojen määrästä.

Tuo "komeetan pää paljain silmin" voi tarkoittaa hyvin juuri ja juuri paljaalla silmällä häämöttävää kuin vähän kirkkaampaakin, jossa näkyy vain koma.
