With a week to go to perihelion, latest observations indicate the coma has brightened to magnitude 1.0
I also notice a few naked eye observations starting to be reported. Have a look at the comet's development in the space of 2 days:

The next few days are going to be interesting as the solar elongation only drops slightly but the brightness increases to perhaps mag 0 or -1. Once the moon is clear of the evening there is chance we may see reports of a tail extending out into the evening sky from high northern latitudes.
