(meteorobs) The Aurigids in 2007: Jenniskens expects a, ZHR of 400+

[Esko Lyytinen]

This can NOT be the same trail that causes the more present uotbursts. 
However these could be from the (then) 1-r trail from the previous 
parent comet return (now two revoltions back).

These two outbursts can be mutually compared, if these are explained by 
a single (then) 1-rev trail, with the elements about those that the 1911 
comet has.
I might be interested to test this, when I will have good time.

If those two outbursts can be mutually linked, then there might be the 
possibility to try to seek the (quite good) timing of the parent comet 
perihelion one revolution ago (back from 1911). There might exist 
multiple solutions.
