(meteorobs) More fireballs with PER than with all other showers?

Hi all,
I agree. I've been observing the Perseids since the 80's (as long as it
was clear), and have noticed more fireballs from the Geminids. Maybe because
they're 'whiter' than the 'yellower' Perseids? They appear brighter? The
Perseids can definitely produce some nice fireballs, but I never really put
them high on the list of "fireball showers." But I'm no pro, so it's just my
observation.

Hi Dan,
I've been watching the Perseids on and off visually ever since 1974
and I must say that I have never really noticed an overabundance of fireballs
from this radiant at all. At least, not relative to other major showers
such as the Leonids and Geminids. In fact, some years have gone by without
me seeing even one fireball from them, even with rates in the 90+ per hour
range. But that's just me, I guess. Other years, I have seen some nice
ones indeed though. I caught only one Perseid fireball in a good look at
the 2012 maximum, for example.
One thing I will say with assurance however, is that I have never seen
the Perseids produce a "fireball shower" year, such as the Leonids and
Geminids have upon occasion, although I may have missed one. Shoot, even the
Taurids have years when fireballs are much more common from them than other
years. The Perseids do, however, produce quite a number of bright, showy
meteors that might actually be below fireball status, but some
inexperienced observers tend to overestimate the magnitudes and call them fireballs
when they may not meet the requirement.
It would be interesting to hear from other experienced observers on
the list of their thoughts on this subject. Estimating magnitudes of
visually observed meteors tends to be as subjective as color determination
sometimes, in my experience (recall the recent discussions regarding "green
fireballs" on the list that went on for quite some time). Video systems would
tend to be more accurate, I would think. Just my "two cents"...;o).
Clear skies to all for the Perseids upcoming, Paul

The statistics reported in
http://science.nasa.gov/science-news/science-at-nasa/2013/26jul_perseids
based on a single fireball camera network should easily be reproduced by
other video observation networks or even in visual meteor data bases - and
the claimed overabundance of fireballs with the PER should actually have
been detected well before if it is as prominent as shown in the history.
Has it?
Dan
