November 20 was the last night to see the comet before dawn in its way to perihelion. At 5 magnitude, to the limit for see it at naked eye. Although not fit in the 1,5º field of image, it shows a long bluish gas tail, inside seems have a narrow orange band caused by sodium emission that only occurs near the Sun.
