* C/2001 Q4 ( NEAT )


It is expected to be 1 mag in 2004 spring. But recent brightness evolution is slower than expected, so it may reaches to only 3 mag at best. In the Southern Hemisphere, it keeps observable in good condition until that time. On the other hand, in the Northern Hemisphere, it is not observable until that time.
