It is certainly brighter at this point -- somewhere in the 16 magnitude range. It is now in the constellation Virgo.
The comet becomes more visible by inverting the colors on the photo below - it is still a barely visible dot.
The comet, as you can see, remains dim. How do I know that particular dot is the comet? By taking several photographs over a three hour period. The dot that moves is the comet.
Drawing an imaginary line between two stars, you can see one dot moving in relation to that line.
How do I know where to point the telescope? The Minor Planet Center (MPC) operates a web page that provides an ephemeris for comets and minor planets. The MPC operates at the Smithsonian Astrophysical Observatory, under the auspices of Division III of the International Astronomical Union (IAU).
