The updated BAA ephemeris is very optimistic giving a maximum magnitude of +4.0 in late feb. I hope they are correct  Smiley
If they are correct, it will be very good for us, 4mag comet is better than 6mag. But why there is so much difference between MPC and BAA predictions?

I don't know either Roman. Some sources go about these calculations in different ways as Brian said. I just hope the BAA are more accurate for our benefit  Smiley. 4th mag is a very respectable brightness, do you remember seeing Ikeya-Zhang a few years ago?. I thought that was a beautiful naked eye comet, in fact, the best I have seen since Hale Bopp because of it's long naked eye tail. I would be delighted if Lulin comes anywhere close to that.
