(meteorobs) May 5th AM 2003 Eta Aq.s from TORNADO ALLEY KS



The deadly twisters split to both sides of me in S KC Metro Area
yesterday afternoon and evening, with a cold front passage squall line
cleansing the humidity and dust out of the air at dark.  With the down to
50 degrees chill there was a heavy dew that I had to
deal with as well. 

Atmosphere very steady, and clear down to 10 degrees above horizon
where it was still a bit hazy.

REMARKS - 50 degrees NO WIND

After I set up the lawn chair and prepared to start the session
I looked high in NW for Z.S. estimate at 344 AM.  Saw three
meteors in less than 45 seconds, incl the final one the best EAq
of the nite a long mag. +2 with a one sec. train in the SW.

The first meteors of the first hr. were Eta Lyrids of med. velocity
within 3 seconds of each other fanning out 90 degrees arc from
radiant, identical +3's. The next two were dim-waked or small
trained Eta Aquarids high in the South at +5 and +6 mag. both
well seen.  Sporadic activity was nearly non-existent.  Northern
Apex produced the 3 nicer random meteors.  The mag. +2 Eta
Aquarid was the last meteor in at around 500AM in the southwest.
Overall a dim effort from the Eta Aquarids, much different that the
late 1970's shows that I remember. 

The Eta Lyrids look like they are alive, too.

Should be clear tonite for max. as well.  Two -3 flares near the
Aquarid radiant made for interesting moments as I locked onto
them, one at 355am just after starting!

If I remember didn't someone last yr. or yr. before have low rates
until nearly May 8-12???  And better meteors too, IIRC.

Am done with the April Lyrid nites stat.s will have them posted soon.
