Reminiscing Comet Machholz and waiting Comet ISON
In the sequence of 12 images depicted the comet Machholz, C/2004 Q1. The comet was captured from 8 to January 9, 2005 by village Livadi, 40km outside from Thessaloniki. The upper sequence of images is the actual capturing and bottom with processing.
At that time the tail of the comet '' projected '' in the star cluster of ''Pleiades'' in the constellation of Taurus, also known as M45, which is depicted on the left. In the images have recorded the two comet tails, the dust tail, heavy dust particles (bottom right near to the Coma head) and the ion tail (bottom left sprawling elongated formation). The formation of the ion tail is an interacting between ionized gases of comet with the ‘’breath of the Sun’’, Solar Wind. This shift in comet’s ion tail, is also due to the solar wind, which ‘’blows’’ the coma of the comet and distracts gases pushing backwards.
The sequence of images covering a total of 130 minutes and shows the relative motion between comet and stars (above) and the moving of the ion tail of the comet (down). The position of Sun is located diametrically in the extension of the straight ‘’ion tail - comet’’. The ion tail is shifting from the comet with velocity about 17km/sec.
