In what can only be described as great good fortune, the weather
forecast for my site proved wrong, and I was treated to a night of
clear transparent skies for the Lyrids, rather than the partly cloudy
predictions. It was not until 4:00 AM local time that I allowed
a few scattered clouds to drive me from my site, but by that time I
was pretty fatigued, after an almost 5-hour observing session that took
place without the benefit of a pre-session nap.
Given my past few experiences over the last five years, this year's
return was about par for the course, for me. This is not to overlook or
ignore Javor's *high* counts and Wes' strong numbers! Things were
very slow at first, but the second half of the third period was
*quite* strong...for what it's worth, I saw 10 Lyrids in one 28
minute stretch (5:35 - 6:03 UT), centered on three LYRs seen
during a single minute at 5:40 UT.
Yet this fine display followed a 35 minute lull during
which not a single meteor was seen, not even a SPO. Activity
was just very uneven. I saw no negative magnitude meteors during
the 4.7 hours I observed. All in all, I observed 50 meteors, 26 of
which were LYRs. It would have been nice to have gotten that last
period before dawn, here's hoping someone else on the US East Coast
managed to do so -- Paul, did you make it?!
This quick overview below shows how uneven the rates were:

Period 2 4:00-5:00UT SPO(4) LYR*(4)* ANT(1)
Period 3 5:00-6:00UT SPO(5) LYR*(9)* ANT(2)
Period 4 6:00-7:00UT SPO(4) LYR*(4)*
Period 5 7:00-8:00UT SPO(3) LYR*(8)* NAPX(1)SAPX(1)
