Unfortunately the stars shown are 10 - 11 mag, when the comet is 5 - 6 mag.  The what's observable page also insisted on downloading the latest java, which was a bit annoying as I've already  got java running.  It then locked up firefox which was even more annoying.  The page shows 273P/Pons-Gambart (not visible) but not 2013 R1 (brightest visible comet), and it isn't on the list of objects to add either.

Jonathan,

Yes, I have rather left the old What's Observable page behind because it 
causes so many problems now that Java has been made so awkward. Despite 
the fact that we have not finished testing it and there are some known 
glitches, you'll be better off with the new version at 
http://britastro.org/computing/applets_ecliptic.html which does show all 
the latest comets.

I should really switch the links so the new page is the first one people 
get to. Sorry to have caused you bother.

Regards,
Graham
