Yep...April Fool indeed. Each year, when Bintel's April newsletter comes out, I'm always eager to look.
As for current comets...
C/2003 T4 (LINEAR) is in the pre-dawn sky at 8th magnitude, a little fainter than had been expected.
9P/Tempel 1 is slowly brightening. July 4 is its big day, when it gets hit with a lump of copper, courtesy of the Deep Impact probe. Some forecasts have the comet brightening to 6th or even 5th magnitude as a result.
Rob McNaught, at Siding Spring, has discovered a new comet. C/2005 E2 (McNaught) may reach 10th magnitude by the end of this year.
...and it's only a year to go until 73P/Schwassmann-Wachmann 3 returns. It makes an exceptionally close passage past Earth and may be visible to the unaided eye.
New Comet.....
