The above is how my Eudora "copied" Kim's posting which was written with
Mozilla 4.05 [en] (Win95; I); the same happens with any Outlook posting
that's not written in strictly ASCII text format. Kim, perhaps you've got
Mozilla set to html or something??
Anyway, Kim said:
" Here are my observations for Tuesday and Wednesday mornings. I did
note one potential Linearid on Wednesday, but it was just as likely a SPO
imposter."
This makes me wonder: we now know how to calculate showers based on dust
trails fairly accurately. But is there a way to calculate the expected
entry velocity of a cometary dust trail, too?? If so, has anyone tried to
estimate the entry velocity of potential Linearids meteors (i.e.: should
they be fast, medium or slow??)?? Wouldn't the entry velocity be related to
the speed of the comet along its orbit and its angle of entry into the
atmosphere, in addition to the usual diurnal variation, of course?? If this
was mentioned earlier, I must have missed it.
" The Taurids, especially STA's, were somewhat active for me. Rates were
not as high as earlier in the week, but the sample (two periods per
session) was smaller."
Tuesday was a very sparse day for me in terms of radio meteors. Today was
about like Monday and all days of last week, however. So far today, no
unusual meteor reflections heard on the ham bands here as of 2340Z, 11
November.
