Look at the date: ..... 13 May 2006.....
I want to know if the three comets is the "same" comet....

What does it say in their SSC file?

Basically it looks like it was once one comet, then - possibly in 1995/1996 - the nucleus split into three chunks, maybe by gravitational interaction with something. So that's why you have three nuclei so close together.

Ooh, boy am I happy you noticed this comet...either way we might get a show... If it hasn't broken totally apart, a 3 nuclei comet, if it has disintigrated more, a potential meteor storm. This is definitely going on the calendar.
http://cometography.com/pcomets/073p.html wrote:The next predicted perihelion date is 2006 June 7 and the comet will pass 0.0735 AU from Earth on May 13, being only slightly farther away than during the original discovery apparition of 1930. Important questions are: Will any of the secondary nuclei still exist? or Will the comet still exist? A meteor shower was predicted and observed by Japanese observers during 1930, with an unexpected outburst of 60 or 70 per hour (this is not a corrected zenithal hourly rate, but the raw numbers) occurring on the nights of June 9 and 10. The possibility exists that another outburst could occur in 2006. If the comet no longer exists as of 2006, a meteor storm might be possible

Will the entire world see it, or just one hemisphere? I ask because I'm going to australia next year with my parents for one month--my first ever overseas trip, and I hope I don't miss the comet(s)/meteor storm!

I probably should've mentioned I will be looking at it through a scope, not naked eye. My exitement over this is as an amature astronomer. Didn't mean to get "naked eye" casual observers hopes up...

Ohh, sorry. My bad. Really, I'm mostly interested in seeing meteor storms; The idea of objects flying into the earth is rather exciting to me.
