It is brightening much faster than expected. It is already so bright as 8.9 mag (Apr. 3, Juan Jose Gonzalez). It will pass 0.85 A.U. from the sun in late June, and it may reach up to 4.5 mag. In the Northern Hemipshere, it keeps observable in good condition for a long time after this, while the comet is brightening gradually. It is observable until around May 25, when the comet will be 6 mag. It will be unobservable for one and a half month around the perihelion passage. But it will appear in the morning sky again at 5.5 mag in early July, then it keeps observable after that while the comet is fading gradually. In the Southern Hemipsphere, it keeps observable all the period until the comet fades out, although it will be low in mid June.
