Has anyone seen anything? ...or even better, have some photographs or video they want to show off?

Cheers,

-Richie,

I stepped into back yard at about 4 am (11 UT) and saw 2 meteors in 15 minutes
while the moonlit sky became more and more hazy. Quit when I could only see a few stars.
At least it wasn't a big trip!

EDIT: didn't see anything tonight frown

Kent was a no-show. Looked NE at about 23:00 just below Cassiopeia and all we saw was light pollution from Maidstone and a bit from London. The general haze prevented any decent viewing, and caused low level reflection from nearby towns...

BBC has some viewers' photos: Link2

Previous years have been good. Maybe next year will be too...

It was a completely clear night in Glasgow. I saw two! No pics though.

It was slightly overcast in Newcastle for the last two nights. Could barely see any stars, let alone any shooting stars.

I did see a dramatic one back in January this year though, whilst driving back through Lincolnshire late at night. Despite being dazzled by oncoming headlights and a slightly overcast sky, it was bright and clearly visible for several seconds before breaking into pieces. Each then faded out before reaching the horizon.

It looked similar to this, but did not light up the sky anwhere near as dramatically as this footage in Canada:

Link2

The next day it was on the news about a turbine blade getting bent on a wind generator in Lincolnshire that same night. I tried to work out from my Satnav exactly where I was when I saw it, and how close to the wind farm. As far as I know there is still no explanation for what damaged the blade, so could it have been another meteor like the one I saw, but that made it to the ground!?!?!? ...or just a coincidence?

Link2

Sorry for the slightly less than reputable source for the story, but I couldn't find any of the BBC links or other papers that covered it at the time.

-Richie,

PS. Also have any of the Radio Amateurs on here managed to achieve propagation via meteor trails? I heard something about them leaving conductive ionised trails that act like momentary long wires in the upper atmosphere.

Hi guys,

I tend to walk randomly outside at night and gaze at the sky from time to time. So I did at the purported peak of the shower - but I must admit I didn't really see any significant increase in meteor count than usual, and I didn't see any specifically bright ones either.
It's usual to see 4-5 here if one gazes at the night sky with concentration for a half an hour or so...

Some were clearly much faster than others - since perseids are comet fragments they are expected to be up to 60km/s, although none of those seemed specifically bright or impressive.

Two weeks ago I saw a nice fireball that illuminated clouds, and could be seen breaking up in pieces before it faded - not closely as impressively as the Canadian video, though. That one looks like it easily released couple kilotons of TNT worth.

Contrary to popular belief, meteors are actually unlikely to completely vaporize in atmospheric entry. They rather tend to break up and lose their kinetic energy, usually resulting in lots of small fragments simply falling at terminal velocity and ending somewhere on earth, which in most cases goes unnoticed.

I don't see, though, how could one make decent meteor photographs without a decent star tracking camera mount.

Persieds are known for being very fast and rather dim compared to other showers like the Leonids.

We had clouds move in right in the middle of the peak (08UT, or 4am local) but before that, we had a peak of about 45 in an hour. The dimmest were probably washed out by the moon, but evidence from other more sophisticated observing stations did seem to show a pretty good peak about when expected.

Last night wasn't bad either, I was still observing 10-15 an hour.

Last night I saw a handful. They were actually fairly bright and had long streaks.
