* C/2004 Q2 ( Machholz )


It will be getting brighter on and on after this, then it will reach to 4 mag locating high in the evening sky in December and January. In the Northern Hemisphere, it keeps observable in good condition for a long time while the comet is bright enough visible visually until 2005 October when it becomes faint as 14 mag.
