2P/Encke It brightened rapidly as expected. Now it is so bright as 7.9 mag (Oct. 16, Juan Jose Gonzalez). It will pass the perihelion on Nov. 21, and will brighten up to 7 mag. In the Northern Hemisphere, it keeps observable in good condition in the morning sky until mid November. But it will be getting lower rapidly after this. It is not observable in the Southern Hemisphere. Date(TT) R.A. (2000) Decl.

However, it faded out unexpectedly around the perihelion passage. Now it is fainter than originally predicted by 4-5 mag. It has already faded down to 17.4 mag (Oct. 1, K. Hills). In the Southern Hemisphere, it keeps observable in good condition while fading slowly after this. In the Northern Hemisphere, it will not be observable after this. Date(TT) R.A. (2000) Decl.

So it was expected to brighten up to 11-12 mag. However, it looked extremely diffuse on July 12 by Michael Jager. So the comet could be already disintegrated at that time.
