Hi Lew:
    I note from your report above, the absents of bright minus magnitude
meteors.  Was this the same for others on the two nights of maximum. As you
know I operate a Sandia All-sky camera from my location and it has a
detection capability of around -3 mag and brighter.  It did not record
anything and the two spectrographs I had set up had negative results also.
I've never seen a year like it with the absents of bright meteors at my
location.  One positive report.  A friend of mine, Garry Dymond from
Newfoundland recorded his first spectrum with a holographic thin film
grating I gave him in 1997.  He had run out of b&w film on his 2-1/4 Sqr.
format camera and switched the grating over to a 35mm which had colour film
in it.  He captured the 1st order spectrum of a -3.0 Perseid on colour film.
Also a bit of the second order.  Congratulations to Garry!  I told him he
would get one eventually if he kept trying! ;-)

Clear skies:
Ed
