Getting higher rapidly in the morning sky. Now it is 6.8 mag (Jan. 23, Alexandre Amorim). It is expected to reach to 5 mag in February. It keeps observable in the excellent condition long time around the highlight until spring. Because it moves along the ecliptic plane, the anti-tail is clearly visible.

Already bright as 12.8 mag, and visible visually (Jan. 5, Marco Goiato). It is extremely low in the Northern Hemisphere now, but observable in good condition in the Southern Hemisphere. It is expected to brighten up to 10 mag from late 2009 to early 2010. Because the comet moves in the southern sky for a long time, it keeps impossible or very hard to observe in the Northern Hemisphere until 2009 September. But after 2009 October, it is observable at 10 mag for a while in good condition. In the Southern Hemisphere, it keeps observable for a long time while brightening until 2009 June when it brightens to 11 mag. But it becomes unobservable around and after the brightest time.

Now it should be brightest. But it has not been recovered yet. It was observed only around the perihelion at the discovery in 1999. If it was bright temporarily in outburst, it can be much fainter than this ephemeris in this apparition. Josef Mueller reported it was 19.2 mag on Dec. 16, 2007, but it was not confirmed. It was not detected, fainter than 19.2 mag on Dec. 20 (James R. Schofer) and fainter than 20.5 mag on Jan. 15 (Leonid Elenin).

It was observed at 18 mag from autumn to winter in 2007. It will be observable again at 18 mag from winter to spring in 2009.

Great outburst occured in 2007 October, and it bacame a naked eye comet of 2 mag. It kept so bright as 5.5 mag still in 2008 spring (Apr. 30, Carlos Labordena), but it was extremely faint and difficult to see. The size was so large, the diameter was larger than 60 arcmin. It will become observable in good condition in this autumn and winter again. The extremely faint large diffuse glow may be detected with a best sky condition, around 5-6 mag with a diameter of 1 or 2 degrees. Mitsunori Tsumura detected a possible glow of Comet Holmes on Nov. 4. Current brightness of the central core is 17.8 mag (Oct. 31, Ken-ichi Kadota), much brighter than pre-outburst brightness still now.

It passed near by earth in October. It brightened more rapidly than expected, and it reached up to about 13.7 mag in November and became visible visually (Nov. 24, Marco Goiato). It will fade out rapidly after this. However, it was still visible as 17.5 mag on Jan. 19 (Y. Sugiyama).

It was observed bright at 16.5-17 mag from late 2006 to early 2007. However, it is fading after that, although it is getting closer to the sun. It was so faint as 19.4 mag around the perihelion passage in 2008 spring (Mar. 10, Mitsunori Tsumura). This comet was observed so faint around the perihelion passage in the previous apparition at the discovery. It faded out before the perihelion passage again in this apparition.
