(meteorobs) Article of very special dust convergence pehenomena from the comet Holmes explosion, in the WGN 41-3 issue

[Esko Lyytinen]

Hi all,

This itemn is not directly connected to meteors but is relevant in 
connection to dust behaviour and meteor trails modeling.

There is an article by me, Markku Nissinen and Harry J. Lehto in the 
upcoming WGN (that unfortunately is a bit late and is not out yet).
We have the permission to make our article public in the net, already. 
And you can get the pdf in the link:

You can see the details of the phenomena in this and also ephemeris.

We observed the phenomenon if February in the Southern sky on the very 
difficults southern Milky Way background with remote controlled 
iTelescopes in Australia, Siding Spring.

And we expect this to be again observable in the Southern sky around mid 
August, and because of this we inform on this now, as early as possible 
for interested observers to get ready for observing. The target is now 
in principle observable maybe about two weeks (with not at all exact 
bounds). Unfortunately during the otherwise best days when the Earth is 
close to the orbital planes, the Moon is strongly disturbing this very 
dim target. But the sky background itself is much more favorable than 
the Milky Way background in February. Very good darkskies will be needed.

The best times to observe in August may be before the geometrically most 
favorable situation, when the moon is still a crescent or later when the 
gibbous waning Moons has not risen yet.

Then, starting probably in November there is expected to be observable 
the convergence at the explosion site in the Northern sky. And the 
osbervation of this is not restricted to when the Earth is naear the 
orbital plane(s) and is expected to keep oservable for two years or 
probably even longer. And this is probably somewhat brighter than the 
already observed and that observable in August, but not for sure, this 
depending on possible further "loss of reflecting material" by 
evaporation or darkening etc.And then one can select observing times 
when the Moon is not disturbing.

Regards,
Esko
