Holmes comet 9 days after the outburst
This image is a result of my cooperation with Arne Danielsen from Norway. It is made of 99 particular
images taken on the same evening from Brno (Czech Republic) and Vestby (Norway). The large number of
images enabled to visualize well all parts of the comet including the very faint blue ion tail, which
was of a very complicated structure. The Holmes comet was on its orbit not very far from the opposition
in respect to the Earth, and since the comet's tail pointed away from the Sun, this means that observers on
the
Earth were looking nearly straight along its tail. Such front view on a bright comet is very
unusual and enabled to make an image with fantastic 3D feeling.
Comet viewing geometry: solar elongation 140.5°, phase angle 14.8°, distance from the observer
1.622 AU, distance from the Sun 2.470 AU.
