Coming Soon - The Perseids Meteor Shower!

Hi all,
stopped for a little while on the way home Saturday night (with Dee) while in the dark of the countryside. As well as noticing nova Chi Cygnii during its flare time, we also looked up to see if there was any Perseids activity.

It wasn't great - during a 10 minute spell, we noticed 4 Perseids and 1 Cygnid. Still, its early days yet. The spreading out of older streams that lie in Earths path mean we will see a rise from now until maximum on the night of August 12th/13th (accurate times etc will be posted later), and then wane to background rates by August 22nd.

I myself hope to have a radio telescope set up as an experiment on the TAS site on the night, where we can actually listen in to meteors as they burn up. I am just waiting on the pen recorder for that!

Incidentally, if you wanted to do this in a simpler way of your own, all you need is a good radio with as large an aerial attached to it as possible. If it is one of those radios that accepts a co-axial antenna, then even better! Turn your FM dial to a part of the band where there are no broadcasts. With luck, you will pick up some bursts anywhere from a brief (but louder) hiss, to a couple seconds of an FM station elsewhere within about a thousand miles of your location!

Post your Perseids observations here as we get closer to the 'fireworks display'!

Oh, even though there will be a 3/4 Moon that night, its still worth a look!

Magic, so if its cloudy, we'll be able to hear what we're missing. :lol:

Cool. I'll bring my scanner too. Whats the best type of antenna to use? specifically that can be built in a few hours next weekend?

I read online that an FM radio tuned to an empty frequency low down in the FM band was the easiest option. However in South Dublin at least that part of the band is very busy.

Actually Seanie, you could just record the static and peeps and sell it to Dave McDonald as background music. Actually it would probably not sound out of place in a night club in Mullingar :-)

Cheers,

You're right about the part of the FM band to use Al. There is a specific FM antenna to use with a particular reciever, though I have caught them with an ordinary 'ghettoblaster' when I was younger. There is a very interesting article penned by our own Sean McKenna about Radio Astronomy. A detector circuit needs to be constructed (very easy) in order to send a proper signal to the pen recorder. Charles from Cork AC knows what I am on about.

Regarding the noise you talk of - in Mullingar, its a different type of noise! And not one readily translatable by any universal translator! :)

I went to bed about 2am this morning. Conscious of the current shower, I thought I'd have a look out my bedroom window, as I often do anyway being interested in astronomy. Immediately, as if it had been waiting for me to look out and straight in the direction I was looking, I saw a fantastic meteor. It was probably the best I have ever seen. It was like one of those halloween fireworks, large, bright green and zooming downwards.

As with any meteor, in an instant it was gone with no evidence that it had been there, but I know I saw it. It wasn't the clearest night, being a bit hazy, but I could see stars. A few minutes later I saw another high above me, and when I looked up, just for a moment there was a streak in the sky, confirming that I had seen it.

I kept a lookout for some more for a few minutes, but saw no more. The two I had seen, especially that first one, were fabulous, so I can't complain. I live in the Dublin suburbs, with light pollution and it was a hazy night, and I can only see a small part of the sky from my bedroom window. So if I can see what I saw, then my advice to you all, is keep an eye out.

I've seen a report of someone else seeing one around the same that I saw that first one and described much as I did. It was in the east or south east, over the Irish sea shortly after 2am. Did anyone else in the Dublin area see it? In any event, Happy star and meteor gazing!

Saw nothing in Celbridge I'm afraid but I've been in the same position as you before - it really is an anspiring sight.

Keep looking up!

Stopped on a bog road on the way home around 02:55hrs this morning. Sky was very transparent and almost looked like Winter. It was nice to see the Pleaides again, nice and high, with Taurus on its side along the horizon.

Spotted 2 Perseids in the 8 minutes I stopped to have a look. 1 came directly from the radiant. Perseus was riding very high. No hint of Moon in the sky either. Pity it won't look like this on Saturday next...

The forecast for next Saturday looks OK. Poor weather all week, but looks like it's going to break for Saturday night. No Rain, 3% cloud. Check out Metcheck.com.
Also the moon will be about 17 deg in the East SouthEast.
Hope this forecast holds (7 days is a bit long).

7 days is abit of a long shot for but at least thats some kind of good news, it would be great if the sky was good for the perseids next weekend.

Seanie and others, I uploaded this 2mb wav to my backup webpage on Eircom, it was recorded at 9-30am this am on 48.2501 mhz, the main carrier is a high powered Tv station in near Madrid. you can hear many meteor reflections, none too dramatic at this time, there is nearly a constant weak carrier probably due to weak enhancement by Sporadic E
All the best and good observing

Sky cleared up for a couple of hours last night for the first time in a month so I went out to setup the scope.

Forgot all about the meteor shower so it was a nice surprise to see a couple streaking in from Perseus as I aligned on Dubhe at around midnight. They really are spectacular.

Pretty neat Charles. So most of those low frequency radar blips are meteors passing between us and Madrid?

Charles,
Is it supposed to be 4 -5 seconds long, thats all I get, I can hear a varing high pitch which I presume is the station, and static in the background, is this the meteor activity?

Guys I just checked Eir-con and the file is 2.75mb, try refresh in ur browser, it is about 2 minutes long, unless u have broadband it will take a while to load, try right click and "save target as..........whatever"
What you skould hear alongside the static or background noise is a carrier varying from time to time due to reflections being picked up on my side from the ionised trails left by meteors, the carrier is not always audible but with high meteor activity multiple long lasting trails allow amazing activity to be recorded at around 50mhz.....
Aurora warning though none detected here at the moment

Dave - I've had this problem with QuickTime opening the source. Its been going on for weeks. The file is large but QT only plays the first few seconds, then nothing. Refresh doesn't seem to help. If I really wnated to listen to a file, I just download it now. But I can't download Charles' without a link on his site...

funny thing there is that I tried do a "save link as" and i got the 2MB+ file but neither quicktime/winamp/wmedia player will open it, and all I get in the browser with quicktime is 5 seconds in firefox, BUT I get it all in quicktime using internet explorer.... strange or what ?!?

Hmmm. I use Firefox and I see the same behaviour as Dave L in that Quicktime won;t play the file. But if I download it it plays in iTunes ok....

I've not used Explorer for a while but I know it plays Quicktime stuff OK.

What's going wrong? Any ideas?

Saw the forecast a few hours ago and it looks good for Saturday and Sunday, so hopefully we'll be in business ! :P

I've just been outside for about half an hour looking for Perseids. Saw 7 in that time, plus 1 sporadic. All were pretty bright - around mag 0.

I thought it was going to be a waste of time with the almost full Moon, and the fact that I live in a suburb of Dublin, where the limiting naked eye magnitude is only +3 on a good night. So I was pretty happy with seeing 8 meteors! And the peak isn't till tomorrow! :D

It's worse than that, it's physics Jim!
