* C/2009 P1 ( Garradd )

Now it is 6.8 mag (Sept. 27, Marco Goiato). It keeps so bright as 6-8 mag for a long time from 2011 to 2012, and will be observable in good condition in the Northern Hemisphere. In the Southern Hemisphere, it keeps observable in mid October.

* 45P/Honda-Mrkos-Pajdusakova

It passed very near by the earth, within 0.1 A.U., and brightened up to 8.0 mag in the southern sky (Aug. 14, Willian Souza). It appeared in the morning sky in the Northern Hemisphere. Now it is very bright as 6.6 mag (Sept. 27, Jakub Koukal). It keeps observable while fading gradually after this. In the Southern Hemisphere, it is not observable until winter when it becomes fainter than 16 mag.

* C/2010 X1 ( Elenin )

It has brightened faster than expected, and reached up to 8.1 mag in mid August (Aug. 19, Michael Mattiazzo). However, it turned to be fading and got diffuse rapidly after that. It has been already became fainter than 10.5 mag and unable to be detected (Sept. 14, Michael Mattiazzo). Altnough it was expected to be a naked eye comet, the nucleus is disintegrating and the comet will disappear soon. However, it was detected by STEREO spacecraft images at 12-13 mag still on Sept. 11 (Alan Watson). It will appear in the morning sky soon, tnen it becomes observable in the excellent condition at midnight. However, the comet can be already too faint to see.

* (596) Scheila

Big asteroid discovered in 1906. It suddenly showed the cometary activity on Dec. 11, probably due to an impact of a small object. It was very bright as 11.5 mag visually (Dec. 17, Juan Jose Gonzalez). It had a dust coma still on Jan. 9 (Joseph Brimacombe). Then it turned to be stellar at 13.8 mag (Apr. 5, Juan Jose Gonzalez).

It brightened up to 17.1 mag in late June (June 24, J. F. Hernandez). It will brighten up to 13 mag in winter. But the condition of this apparition is bad, and it will not be observable around the perihelion passage. It will appear in the morning sky at 14 mag in 2012 April in the Southern Hemisphere. It will not be observable until 2012 June in the Northern Hemisphere, when the comet will be 15.5 mag.

It was expected to keep 14-15 mag for a long time from 2011 summer to 2012 summer. However, it is lost. It was observed only during two days in 2010 June. So the orbital elements are extremely uncertain. The condition is good in the Southern Hemisphere. But in the Northern Hemisphere, it is not observable until 2012 August.
