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). Now it is extremely faint as 21.2 mag (Apr. 20, J. V. Scotti). 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.
