Once has reached enough altitude in the sky at dawn in Northern Hemisphere, with a brightness of 6.5 magnitude the comet shows a spectacular display of tails: a narrow and long ionic tail of bluish tone with several degrees of longitude that leaves the field towards West (upwards), other most brilliant and short dust tail of white-yellow tone formed by heavy dust particles that remain as a trail in the orbit of comet towards southeast (to right-bottom) and finally, located between both, one tail more faint and wide with fan shaped and more whitish formed by fine dust grains released after the comet perihelion. The redish star below the comet es Upsilon Virginis with 5.1 magnitude and the more visible galaxy at top beside tail is NGC 5496.
