This is also a great site that I check regularly - tells you whats out there, what mag, whether its fading or brightening, with finder charts.

As Stephen says, there are 3 out there at the moment, under mag 10. K5 is fading but still pretty easy, but the other 2 are brightening so you will have a good chance to see them. They will look like fuzzy spots at the moment but as they become closer a tail may be spotted.
Good luck!!
