Best time and the azimuth, altitude (A,h) are at lat. 35 deg in the Southern Hemisphere. Azimuth indicates 0 for south, 90 for west, 180 for north, 270 for east.

C/2013 R1 ( Lovejoy ) Now it is so bright as 6.0 mag (Nov. 8, Seiichi Yoshida). It will pass only 0.4 A.U. from the earth, and 0.8 A.U. from the sun in November and December, and will brighten up to 4-5 mag. In the Northern Hemisphere, it keeps observable in excellent condition for a long time until 2014 autumn when the comet will fade out. In the Southern Hemisphere, it is not be observable from mid November to early February. Date(TT) R.A. (2000) Decl.

It will approach to the sun down to only 0.01 A.U. on Nov. 28, and is expected to be a great comet. But actually, it is fainter than originally expected by 3 mag. It will be 3 mag at best when it is observable in the morning sky. The brightness evolution is getting slower recently. The condition is excellent in the Northern Hemisphere. It keeps observable almost all through the period of brightening, at the highlight, and of fading. The condition is not good in the Southern Hemisphere. It is not observable at all the latter part of the highlight, and it keeps low all through the period. Date(TT) R.A. (2000) Decl.

It will be fading after this. But it may keep 16 mag some more time. It will be getting higher gradually in the Southern Hemisphere. But it keeps locating extremely low in the Northern Hemisphere.

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. No observations have been reported after that. It keeps locating in good condition after this in the Southern Hemisphere. It is not observable in the Northern Hemisphere. Date(TT) R.A. (2000) Decl.
