Hi Justin, thanks for your comments. The ephemeris lists the magnitude at 19.3 for last night, but I have been informed that, the magnitude is only based on nucleus and corona from figures done back in December. And seeing there is no nucleus or corona the magnitude is anyones guess. Also as magnitude is based on a point source and not a diffuse object it would be hard to work out such on this.
I would be very interested to know also what the magnitude is. It is many times fainter than the Witches Head nebula.
All the best.
