There is indeed no "freshly" ejected fragment or whatever (=released
since 1995) going to hit the Earth this year from comet 73P, according
to our calculations. The reason is that the ejection velocity recquired
to do that is way higher than what can reasonably be.
Hi Jeremie --
No . . . when I inquired about the dust released from 73P after it
fragmented
in 1995, I was NOT making reference to its effects on Earth THIS year. What
I
was referring to was the possible interaction in the year 2022. In your
graphic
for that year, you depict two "double pronged" dust trails from 1892 and
1997
that could possibly cause a meteor outburst.
However, in a 2001 WGN article by Hartung Luthen, Rainer Arlt and Michael
Jager,
they predict that the debris cloud that was shed after the comet broke apart
in 1995 should pass within 0.0004 a.u. of Earth on May 31, 2022. I was just
wondering if you had taken that 1995 dust cloud into consideration for 2022?
That fact that you show trails from 1892 and 1897, but not 1995 seems to
indicate
that either you didn't -- or -- perhaps your calculations differ from
Luthen, Arlt and Jager's.
Also . . . check your diagram for the Tau Herculids in 2039 . . . in your
paper you
indicate that the year for Earth interaction with the dust trail is in 2049.
So which year is correct?
