???????I have to remind myself that we, as humans, are witnessing this comet's behavior  for the very first time.  Technology has advanced considerably since this comet's last 1956 return.  We as imagers are here to document every comet's "personality" for future generations of enthusiasts to come.
 
 
 
Cheers to today's comet enthusiasts!
