A colloquial direction and directional modifier referring to a direction between north and west. As with both of those terms, it can be used either in an absolute sense (relative to the real and imaginary axes) or as a relative direction (relative to a mu-molecule).
The colloquial term "northwest radical" refers to R2.2/5, because it touches R2a on its northwest side. Note that this is not the same place in the Mandelbrot set as the northwest external angle, which is at R2.1/2.1/3.
