It reached up to 8.4 mag in October (Oct. 20, Marco Goiato). It is bright as 9.4 mag still now (Nov. 12, Marco Goiato). It keeps observable for a long time until 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.

It reached up to 7.7 mag in summer (Aug. 13, Chris Wyatt). It is fading now, but still bright as 9.3 mag (Nov. 8, Juan Jose Gonzalez). It will be unobservable soon. In the Southern Hemisphere, it will appear in the morning sky in late February, then it keeps observable for a long time. But in the Northern Hemisphere, it is only observable in the low sky in 2010 spring, then it will never be observable again.

* 169P/NEAT

Although CCD observers reported it as faint as 15-16 mag, it looks bright visually as 12.9 mag (Nov. 18, Alan Hale). Juan Jose Gonzalez reported it was significantly bright as 9.2 mag on Nov. 18. It is expected to reach up to 10 mag in December. In the Southern Hemisphere, it keeps observable all through this apparition, although it becomes low in November and December. Especially, it will be observable in the excellent condition after January. In the Northern Hemisphere, it keeps observable in the evening low sky until late November when it becomes 11 mag. It will appear in the morning sky at 14 mag in late January, then it keeps observable while fading gradually.

* 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.

In the Northern Hemisphere, it keeps observable in good condition for a long time until 2010 spring when it becomes fainter than 18 mag.
