Veli-Pekka Hentunen, Warkauden Kassiopeia
Last night 10.9. at 02.06 an exceptionally strong fireball flashed above the Härkämäki observatory. Its brightness was in the order of a full moon. Seen from Härkämäki, the object exploded to the south at an altitude of about 45 degrees in the constellation of Pisces. The target arrived from the direction of the constellation of Perseus and left a tread about 30 degrees long before the explosion. There was still a large cloud of smoke in the sky for about 25 minutes. In the pictures taken by Ursa from Mikkeli, the same fireball can be seen in the north direction, behind Otava!

Veli-Pekka Hentunen, Warkauden Kassiopeia
The fireball was clearly in the image of the Härkämäki Observatory's sky camera, even though the sky was cloudy throughout. Only the brightest stars were faintly visible in the sky. The fireball began to appear about 30 degrees above the horizon and brightened very strongly right on the horizon.

Binocular comet Wirtanen

Esa Heikkinen, Anni Heikkinen, Veli-Pekka Hentunen, Warkauden Kassiopeia
Outgoing Wirtanen photographed with a CCD and digital wit. In the second CCD image, the stretch of the image is knocked out as much as possible so that the entire comet material becomes widely visible. Wirtanen fills almost the entire field of view, thus being at least 20 arc minutes in size and perhaps slightly egg-shaped, so the tail could be right downward. CCD images are 18 'x 23' in size. Illustrated by Anni and Esa Heikkinen, processing of CCD images Veli-Pekka Hentunen.

Another comet 64P / Swift-Gehrels was also filmed as a short clear section on Thursday night. 10 of these were taken. a series of 120-second L exposures, no more weather would have been enough. Like Wirtanen, this comet also appeared quite large, about 10 minutes of arc. The picture clearly shows maybe two very close jets of material to the left, slightly downhill. Image size 18 'x 23'.
