Notes. r and Δ are the heliocentric and geocentric distances, respectively, α is the phase angle, and GL the galactic latitude of the comet. The average nightly sky conditions are reported (PHO = photometric, CLR = clear) as well as the type of observations performed (IM = imaging, SP = spectroscopy).
From Tubiana et al. (2008).
