Now it is 7.2 mag (Oct. 4, Peter Bus), much brighter than originally expected in the extremely low sky at dawn. It will approach down to 0.4 A.U. to the sun on Oct. 28, and it will reach to 4 mag in mid October. However, the condition in the Northern Hemisphere is very hard. It locates extremely low, slightly over the horizon, in the morning sky from late September to mid October, and in the evening sky from mid October to late October. Then it will never be observable again. In the Southern Hemisphere, it will appear in the evening sky at 4-5 mag in early November, then it keeps observable while fading gradually, although it will not locate very high.
