Perseid meteor shower 2007
by Simon at 15:39 06/08/07 (Blogs::Simon)
I've been watching this shower since I was about 12 - the annual Perseid meteors make their appearance this weekend, and this year there's no moon to spoil the view.
Maximum is around 02.00UT (3.00am BST) on the 13th August, but it'll be worth watching any clear night from now - they'll be there, but at a much lower rate - maybe one or two an hour tonight, usually reaching around 80m/hour at the maximum.

Two years ago I saw a few hundred meteors over the course of 4h from 11pm from a dark sky site on Salisbury Plain - it's well worth getting away from light pollution if you can, to best appreciate the fast-moving shooting stars that appear to radiate from a point in the NE of the sky on the Perseus/Cassiopeia border between the recognisable W of Cassiopeia and the NNE horizon (though you can see them all over the sky, not just in that little area)

Best technique I've found? Lie on your back on a mat on the ground, or in a reclined deckchair facing NE but gazing upwards. Try to get as much sky into your field of vision as possible and relax :-) You'll hopefully start seeing them after about 20 minutes, when your dark adaption's improved.

Occasionally I've seen fireballs (streak followed by very bright flash as the particle vapourises), very often I've seen trails that linger in the sky for a few seconds or longer (ionisation), but mostly they're quick streaks of light about the brightness of the brightest stars.

Clear skies!

If it looks like it's going to be clear on Saturday or Sunday, I'll text you and we can take it from there.

I'm afraid that was a couple of days ago. The shuttle is now attached and they are in the middle of a space walk at the moment. if you go to the NASA site you can download real-time TV images. The space station/shuttle went over this evening at 9.45pm

Thanks Patsy - found the NASA ISS Timings site and there's another good pass this evening just after 10pm from our location.

I have been going out every evening for the past week as the ISS is passing this way for about a fortnight. I have just come in now from watching the meteor shower - I counted 34 in 16 mins. Some of them took up half the sky - the best I have seen for many years, it's normally too cloudy. Might go back out at about 3am if I wake up.

I went out around 11pm last night and stayed until 4am this morning - I'm lucky enough to have 360 degrees of open sky and very little light pollution here - and saw over 400 with some pronounced peaks in activity towards the end. I do like the flurries of activity that mean you get half a dozen in the space of a few seconds from time to time.

I've been watching this shower for many years, and agree this was one of the best shows I've seen too. No moonlight makes a lot of difference.

Saw quite a large number of meteors that didn't appear to come from the Perseid radiant too - though whether those were really 'sporadic' meteors or actual Perseids that had been whipped around in Earth's gravity well and fell in from a different direction I don't know.

That's 400 over 5 hours, remember :-)

It was quite eerie being up on that ridge on my own - all kinds of munching, trit-trotting and rustle-rustle type noises, and one *particularly* loud mosquito made me jump.

I'll keep an eye on the SPA mailing list to see if anyone else reports similar (they track fireballs)
