(meteorobs) 02 Leonids from St. Augustine - narrative report




Greetings to all,

      No one was more surprised than I was when it turned out that N. Fla 
was the place to be for the 02 Leonids!  Given our track record of weather 
in November over the last thirty years or so, it would have been a long shot 
to expect this to say the least.  We have now had two perfect years in a row 
for them.  I had checked out the water vapor satellite images on the 
Hurricane Center's Tropical Storm prediction website during the day of the 
18th and saw the driest air in the whole eastern hemisphere sitting right 
over us!  But there was still that darn lunar situation to contend with.  At 
the last minute, I decided to forgo the midnight "grazer window" and get 
some sleep in anticipation of what was to come.  I figured the moon would 
take the edge off any grazers that came through and I had seen about a dozen 
gorgeous ones last year, enough to hold me over.  As it turned out I 
probably would not have seen many anyway due to the intrinsic faintness of 
the 02 Leonids. It's better to be lucky than good, any day I say!
    I arose at 4 a.m. local and walked the 100 yards or so from my front 
door down to the west bank of St. Augustine Inlet-the extent of my travels 
this year!  The moon was still hanging fairly high in the west. I set up my 
observing chair and sleeping bag on the seawall, carefully positioning the 
moon behind a couple of trees, out of sight, out of mind. It was clear to 
the horizon looking north, east and south.  Only a few trees to the west cut 
down my view.  I was about 500 yards or so north of the Castillo de San 
Marcos National Monument, the 300 plus year old Spanish fort in St. 
Augustine.  Except for the lingering moonlight, conditions were picture 
perfect.  Humidity was remarkably low with minimal dew and no fog, a rarity 
for this time of year in N. Florida. Again, good fortune seemed to be on my 
side.
    I began obs at 4:30 a.m. local, to relatively low activity.  Typical 
Leonid behavior:  a burst of two or three in a minute, followed by five or 
so minute lulls.  Didn't take long to notice that a majority of the Ls were 
hitting very faint and short-pathed, some +3s, but most were +4.  
Occasionally, a nice +2 would hit leaving a beautiful softly-glowing, bluish 
train against the sky in its wake.  Nothing unusual here:  textbook Leonids, 
in fact.
    It was fast approaching 5 a.m. local, the skies were improving as the 
Moon headed for the horizon, but the Leonids were not.  Still keeping the 
same steady pace.  No sign of any ramp up whatsoever.  Some concern 
beginning to grow here.  Where are they?  Could the storm predictions be 
wrong, Heaven forbid?  I decide to hang in there a while longer and see what 
happens.
It's now 5:15 a.m. and maybe I'm beginning to catch a slight upswing in the 
Leonids "beat".  The two or three mini-bursts are maybe coming a little more 
frequently now.  But not by much!  My concern is growing.  They are still 
faint, short and near the radiant, only an occasional + 1 or +2 with a train 
keeps me going.  Nothing even close to minus magnitudes, let alone a 
fireball!  Who could have figured this?
    Just before 5:30 a.m., my inner voice is trying to get me to give it up. 
  Moon is gone, but twilight is soon to come.  No storm in sight!  What is 
going on here?  Nice Leonid shower in any other year, but not this one!  My 
refusal to quit keeps me in place.
    Finally, just after 5:30 a.m., things start to happen.  I begin to see 
the beginning of a modest ramp-up!  Still two or three Ls hitting in short 
bursts, it's just that now the lulls are not so long in between! A minute or 
two later and the lulls are gone!  Two or three Ls EVERY minute! Now we're 
getting someplace!
    It's now pushing 5:40 a.m. and dawn is kicking up over in the east as 
Venus smiles back at me.  Leonid streaks are starting to flash everywhere at 
about 5 a minute now.  They are hitting at all points of the compass in 
quick succession.  I see L streaks leaving trains but no meteor that caused 
them!  A beautiful 0 mag hits in Leo Minor, its train hangs there, two more 
off to northeast!  Now we're talking.
   At 5:45 a.m., I am startled by a human figure standing next to me!  It is 
my down the street neighbor!  He has ventured out to see what is going on.  
He says the local TV station is reporting that the storm is happening big 
time. I think: maybe so, but not by much!  It is his very first meteor 
shower, he is blown away!  It is my about two hundreth meteor shower and I 
am soon to be blown away, too.  Just after he shows up, the defining moment 
of the morning occurs:  a "squadron" of no less than eight identical +3 
Leonids streak out the radiant going NW in Gemini.  They are perfectly 
simultaneous and about three degrees away from one another.  I almost come 
out of my observing chair!  Within that five or so second bin I see no less 
then 15 to 20 Leonids hitting everywhere on the sky.  I get the "wheel spoke 
effect" and visualize the Earth's movement in space.  I can't believe this 
is happening!  All I can think of is the classic photos of the 1966 storm 
that we have all seen.  I never could grasp what 40 per second must have 
looked like back then.  Now I can!  Even if my brief encounter with 8 to 10 
per second still pales in comparison.
    After this, the splendid Leonid "back beat" of one per second continues 
on for a few more moments, then fades.  It is obvious the peak has passed, 
but my euphoria hadn't.  And still hasn't.  No real fireballs for me, only a 
few popped in negative magnitudes and no long enduring trains, but I could 
not be happier at the brief, stunning spectacle I have just seen.   Regards, 
Paul in FL
