The folks at S&T have just added an updated article with more observing tips. They mention in this article that the comet is moving north across the sky at a rate of 2° per day so if you had these finder charts and for some reason you did not have data on the Moon, you as a navigator could use the comet's position to determine GMT within an hour or so. Not much use unless you've somehow lost the date --for example, you've been through a storm for a few days, you're exhausted, and you're not sure whether today is Monday or Tuesday.
