I observed other comets in addition to this list, but some I could not get (or simply did not make the effort on) a second chance at drawing (or movement noted), so they do not count toward this Astronomical League effort (unless a tail is seen).  My apologies on my “artwork”.  I am a “stick-figure” kind of guy when it comes to drawing.  However, I can say that I have gotten better (with respect to comets) with time.


 
Some personal statistics of these observations thru June 6, 2016:
# comets observed  =  37
# comets with definitive tails seen = 13  (rest were 'fuzzballs')
# comets observed either naked eye or binos = 19   (binos are an essential tool)
# comets observed by unaided eye= 6 (17P/Holmes,  C/2006 M4 Swan, + 4 below)
# comets with naked-eye tails observed = 4  (these are special:  Hyakutake, Hale-Bopp, C/2006 P1 McNaught, and C/2011 L4 PanSTARRS)
