(meteorobs) Leonid Observations 11-19/20-03 East Georgia
Last night' s two hour session proved to be
quite satisfying given the lowered expectations I had driving out to my sight.
It turned out I had 21 Leonids my first hour and 15 LEO's the second hour, 36
total for two hours teff (the numbers I posted this morning were off the top of
my head, and too conservative for the LEO's). This was in addition to the
strong SPO and Taurid rates, which boosted the entire session to 65 meteors
total. I did not observe for the apex as I didn't have the coordinates nor the
time to calculate them, but what appeared to me to be obvious apex meteors were
seen, logged as SPO's. There were a couple of short Taurids which I didn't
get a clear look at, they were listed as TAU while the rest seen were
STA's.
My rates were right in line with what
Paul Jones reported earlier for this morning, our longitudes are similar and
he's only about 250 miles south of me. His one hour period basically took up
where my last hour was leaving off, and for all practical purposes, he was
seeing what I was seeing.
The highlight
was a -3 sporadic that dropped down to the left of LEO moving quite slowly; it
was golden yellow. Several foreshortened Leonids were seen at the radiant,
and *many* of the trains lasted multiple seconds, the longest two being seven
seconds. Among other highlights were the mini sporadic "outbursts",
which on two occasions saw three unrelated meteors appear within seconds of each
other. The LEO's tended to come in clusters of two several times.
