* 88P/Howell

Now it is so bright as 8.5 mag (Oct. 13, Marco Goiato). It keeps observable for a long time until 2010 February. It will keep 9 mag until the end of 2009. But in the Northern Hemisphere, it keeps very low after this. It locates a bit higher in the Southern Hemisphere.

* C/2006 W3 ( Christensen )

It reached up to 7.7 mag in summer (Aug. 13, Chris Wyatt). It is fading now, but still bright as 9.1 mag (Oct. 13, Alexandre Amorim). It will be getting lower gradually after this, and will be too low to observe in December. It keeps observable for a long time after 2010 in the Northern Hemisphere. But in the Northern Hemisphere, it is only observable in the low sky in 2010 spring, then it will be unobservable after that.

* 217P/2009 F3 ( LINEAR )

An outburst occured on Oct. 13, and it reached up to 8.5 mag on Oct. 15 (Toru Yusa). The central nucleus shined like a bright star, and the dust coma looked like 17P/Holmes in outburst. However, the comet returned to the normal state within a few days. Now it is 9.5 mag (Oct. 17, Katsumi Yoshimoto). It will keep 10-11 mag until December. In the Northern Hemisphere, it keeps observable in good condition for a long time until 2010 spring when it becomes fainter than 18 mag.
