Denis,

So C/2013 V3 (Nevski) is now also on the charts page.

Is my latest addition of perihelion times useful to observers? Perhaps 
we should show other data too (if so, what?). The chart generator could 
be made to output such things as part of the HTML it already creates, so 
it would not add any additional burden for me when revising the charts.
